because Apache::Registry overrides Perl's builtin exit() in the compiled
script (which has it's own unique namespace).  you're calling exit() in a
different namespace, so exit() is now Perl's builtin exit.  the builtin
exit() calls a c-level exiting, killing the process before Apache's output
buffers have been flushed.
if you're using Perl 5.005+, exit() should be overridden everywhere, what
version are you using?
