Interesting.  I just accessing my 'view' page template.  Eventually, the
_resize method gets called and that's where the popen2 hangup happens. 
It's even more wierd that the same popen2 call doing the same thing works
fine outside of Zope (i.e. interactive python prompt.)

I'm wondering if my system is over optimized (-O3)...

Please do share the script.  I'm building PIL now :)
