I don't know why, but commenting out the exit fixes it for FreeBSD (v5.8.0 built for i386-freebsd). Why would calling exit in the child exit the parent?

Update: The parent doesn't exit. $SIG{'CHLD'} is being called, but accept is returning false due to "Interrupted system call" ($! == 4). Maybe the CHLD signal interrupts accept?? no, that can't be it, cause it works fine without the call to exit. In any case, the following fix seems to work:

use POSIX;

...

REDO_ACCEPT: {
  while ($client = $sock->accept())
  {
     ...
  }

  redo if $! == EINTR;
}

There might be a better way. I'm not familiar with this stuff. I just deduced this from debugging.
