Hi Jan,
thanks for answering.

You can use the Perl kill() function to terminate a thread, but it has
the same limitations as the alarm() function on Windows: it will not
interrupt a blocking system call (e.g. a blocking socket read). The
kill signal is essentially delivered by Perl's safe signal mechanism to
the other thread.
perlfork tells me this:
kill() can be used to terminate a pseudo-process by passing it the ID
returned by fork(). This should not be used except under dire
circumstances, because the operating system may not guarantee integrity
of the process resources when a running thread is terminated. Note that
using kill() on a pseudo-process() may typically cause memory leaks,
because the thread that implements the pseudo-process does not get a
chance to clean up its resources.
That's not what I'd call "safely".
Or is that warning outdated?
