Installing a custom signal handling subroutine is a lot like playing with fire. it may seem like a lot of fun, but, sooner or later, you're going to get burned unless you're exceedingly careful. by installing perl code to deal with signals, you're exposing yourself to two dangers. first, few system library functions are re-entrant. if the signal interrupts while perl is executing one function like malloc 3 ; or printf 3 , and your signal handler then calls the same function again, you could get unpredictable behavior - often, a core dump. second, perl isn't itself re-entrant at the lowest levels. release 5.005 of perl supports lightweight processes called threads. ; if the signal interrupts perl while perl is changing its own internal data structures, unpredictable behavior may result - usually random core dumps. you have two options: be paranoid or be pragmatic. the paranoid approach is to do little as possible in your signal handler, as exemplified by the eval and die code in the solution - set a variable that already has a value, and then bail. even this is cavalier for the true paranoiac, who avoids die in a handler because the system is out to get you. the pragmatic approach is to say "i know the risks, but prefer the convenience, " and to do anything you want in your signal handler. signals have been implemented in many different operating systems, often in slightly different flavors. the two situations where signal implementations vary the most are when a signal occurs when its signal handler is active reliability ; , and when a signal interrupts a blocking system call like read or accept restarting ; . the initial implementation of signals was unreliable, meaning that while a handler was running, further occurrences of the same signal would cause the default action, likely aborting the program. later systems addressed this each in their own subtly different way, of course ; by providing a way to block the delivery of further signals of that number until the handler has finished. if perl detects that your system can use reliable signals, it generates the proper system calls to achieve this saner, safer behavior. you can use posix signals to block signal delivery at other times, as described in recipe 16.20. for truly portable code, the paranoid programmer will assume the worst case unreliable signals ; and reinstall the signal handler manually, usually as the first statement in a function: $sig \&catcher; sub catcher \&catcher; # . ; in the special case of catching sigchld, see recipe 16.19. system v has bizarre behavior that can trip you up. use the config module to find out whether you have reliable signals: use config; print "hurrah!\n" if $config.

For isps just starting out with a desire to become a tier 1 isp, the selection of transit supplier s ; is important. since "once a customer, never a peer" will prevent peering with tier 1 isps at a future date32, it is often more cost effective and strategically more effective to purchase transit from a large tier 2 isp. as the network traffic grows, and the isp network expands into peering points, peering can effectively reduce the cost of transit. once enough peering points are activated, enough traffic is carried, and once the peering prerequisites are met, discussions with the tier 1 isps can begin. not being a customer of the tier 1, means that no revenue is lost by peering, and therefore there is one less obstacle to overcome33.
