Jeremy,
I assume you are probably running the POE version installed through
ActiveStates ppm.
This seems to have issues and I found that by installing through CPAN
that there is a newer version of POE that seems to have a lot of
performance issues fixed. Rather than installing through active states
ppm (which seems to be behind a few POE versions), you can install POE
through CPAN:
perl -MCPAN -e "install POE"
See if that helps at all.

I'm building a Win32 POE application that need to make a non-blocking
call to a function in an external Perl package. This function takes
references to Perl objects and array references (however no subroutine
refs).
I've looked at the options for completing this sort of task with
POE::Component::Child & Wheel::Run + Filter::Reference, however there
seems to be one limiting factor here - Win32 fork emulation.
The Win32 fork emulation seems very buggy. In tests I've used with
Wheel::Run I get fork failures ( i.e. "fork() failed: Resource
temporarily unavailable") after the 64 calls of fork from the parent
process. See the attached simple example that demos the error:
use strict;
use warnings;
my $COUNT = 0;
my $MAXFORK = 2**6;
while ( $COUNT <= $MAXFORK ) {
my $pid = fork();
die "fork() failed: $!" unless defined $pid;
if ($pid) {
$COUNT++;
print "Fork count $COUNT\n";
}
else {
# in child
exit(0);
}
}
Also when running a code subroutine, passing in variables, with
Wheel::Run and Filter::Reference I get huge memory leaks after the
forked off child thread exits. I can't exactly track where the leaks are
occurring, but it seems to have something to do with including packages
at runtime using the "require" keyword. I also get the same issues with
POE::Component::Child which is no surprise considering it also uses
Wheel::Run + Filter::Reference.
I was hoping if someone might have any suggestions as to how I might
come up with a solution to this problem. Moving from Win32 to *NIX is
not an option.
I have thought about using Win32::Process and running a Perl process in
the background (so the kernel can take responsibility for the memory
allocation etc) and then having a POE delayed event that checks every
second or so to see if the process is complete. I'm however unsure on
how to pass specific runtime variables to the spawned off Perl process.
Any help on fixing POE::Wheel::Run or providing another solution would
be greatly appreciated.
I'm using WinXP SP2, ActiveState Perl v5.8.8 Build 820 and POE 0.9917.
Thanks
Jeremy
