raise exceptions yet but I am still getting really long pauses (~15s).  T=

occur mostly when opening a new client connect and therefore doing a=20
db.open().

I'll try windows.....
better, but still not working.  Now local connections on windows experien=
ces=20
random pauses (not during connection but while looping to create new=20
StorageObjects) but exceptions aren't raised.  A remote connection howeve=
r=20
raised the attached traceback. =20

I could still connect to and use the windows server though.  I need to=20
implement the retry code on ClientDisconnected, but the IndexError will b=

up my code without retrying.
