Of course there are. One example is weather
select
provides the remaining time, and weather it restarts after
a signal. This is system-dependent, and ultimately depends
on what the kernel and the C library does.

I don't see how this is related to unspecified behaviours I was talking about. Here select is clearly system-dependant because it precisely depends on the one provided by the system (and it doesn't depend on C at all, there's no select in C).

You were talking about system dependencies:
Well since perl is written in C, there
could be unspecified behaviours in Perl itself
(ie. having different valid results for the same code
with different platforms),
Platform and system means almost the same here, doesn't it?
(and it doesn't depend on C at all,
there's no select in C).
What do you mean here "not in C"?
Select is a system call, so what it does with the time
is an issue of the OS kernel, but
the restarting of system calls after signals is
handled by the C library IIRC.
(Or doesn't it, does the
kernel restart syscalls if you say so with sigaction,
maybe libc just sets the default behaviour to what you
want, I'm not sure).
