[ZODB-Dev] ClientDisconnected error on windows

Didn't work for us.  Also, on linux we get really long pauses where there=
 is=20
no CPU being used - I can only presume python is blocking on the socket.

What can I do to capture more detail?  We should be able to package up a=20
reproducible test case - is that the best thing?

What I can package is our use of ZODB for omniORB.  It would require you =
to=20
have omniORBpy installed but then it should be trivial to run our code.  =
Do=20
you want this?

The only other thing I can mention right now is that we are getting these=
=20
errors during stress testing - multiple threads hitting our server full o=
ut.
