If I had this problem (I would be on Unix, then), I would use
GDB (the GNU debugger) to attach to the process and see what
Zope does. It is a bit tricky to analyse a Python program
with a C level debugger. But, usually, I get valuable insight
into difficult problems, this way.
Now, you are under Windows. But, maybe, there too is a debugger
* attach a running process
* display and analyse the threads in the process
* support casting and inspection of cast objects.
Then, this may be an option for you, too.
