Exactly.  Even constraining httpd to smaller stacks is unlikely to be wise
with mod_perl running, consider the default is 256kb IIRC.  Shrinking this
to 128k obviously is a big help, but is unrealistic.

I agree with Peters, run a proxy in front of the server hosting mod_perl.
Even when we ship binary 64 bit for win32, there are far too many broken
perl and similar modules which don't expect sizeof(long*) > sizeof(long),
which has tripped up many porters.  Most of these defects are gone from
apr and httpd, and perl and modperl can likely catch up quickly, but to
isolate every possible modperl XS package on cpan and identify all those
which make stupid long x = (long)xptr; assignments will be arduous.
