But I think we can ignore all those questions, because I don't see a need to work with this example. I'm just looking for someone to tell me how alarm works. A few sentences in English will be fine. No code really need be written.
Old multi processor systems used two methods for interrupting the current process/thread -- hardware timers and/or software signals. The method Perl (and most modern systems) uses today is software signals. Think of it as a polite way to say PMFJI to the current thread/process. The alarm simply installs a kernel-level process to "interrupt" the target thread/process when a previously determined "event" occurs.
