[mod_python] Session problems

Take out sess.unlock(). There's no need to do this as it's handled by
the class itself by default.  This could have perhaps lead to
MemoryErrors.

----
Thanks Chris.  I removed the unlockm,, but still no luck.  The problem
seems to be with the following statement:

sess['ddcSearch'] = ddcServer.ddcSearch 

If I comment that statement out (and the following load for ddcSearch)
then it works.  Otherwise it fails on the 'sess.save()' statement.
ddcSearch is a fairly large and complex object.  Does this matter?  I'm
running apache 2.0.40 and mod_python-3.1.3.  

Thanks!  harry
