Well, that has the builtin assumption that the max fileno is 100, which is probably good enough, usually, but it will lead to a really hard to debug problem, eventually. It's actually somewhat of a weakness of perl, I think, that there is no exposed system call to get all open file descriptors. Obvoiously you can deal with this if you compile perl properly, and just refer to the system call by number through syscall()... but still, this is sad.

This is additionally sad because of the behavior of perl's output buffers on fork() (leaving buffers unflushed), since the buffers are duped with the fork, but there is no means by which to systematically flush all buffers before fork(). However, as I understand it, the behavior on fork() is fixed in later versions of perl (I'm still on 5.005_03... but we're working on an upgrade plan to 5.8 soon)... so that's good at least.

Not an editor command: Wq
