[Zope] gotcha for zope on solaris2.7 - make sure you use pthreads.

[Anthony Baxter]

If you're running a Zope on Solaris2.7 and you're seeing strange
behaviour, make sure that your python executable's been built and
linked with pthreads, not solaris threads. I've just had a horrible
time figuring out why I was seeing very strange behaviour on Solaris
until I noticed this. 

ldd `which python` should show /usr/lib/libpthread.so, NOT 
/usr/lib/libthread.so.

Anthony, bitter and twisted at Sun.
