...the difference between a thread and a process...
If you're using Perl threads, you shouldn't have to worry about whether it is actually implemented using processes or real threads™. That's why they're "Perl threads".
Having said that, to my knowledge, Linux is the only system where you can actually think of threads as processes, as having seperate program id's (pid's, $$). This allows modules as Thread::Signal to function in that environment. Win32 only knows about real threads and mimics fork() using threads. Other *nixes are somewhere inbetween. Some can fork() and have real threads (Solaris seems to fall in that group). But e.g. on Mac OS X (and presumably other BSD's), threads look as seperate processes, but can not be signalled.
...never-ending sub (ie it's got a while (1) loop)m how can I stop it nevertheless?
Use a shared variable in the while. So:
and reset the shared variable in another thread when you want to have the thread in question stop.
Hope this helps.
