Thread local problems

[Randy Syring]

Phillip,

Its possible that I am mistaken, but I think the attached test script
demonstrates that something in PyISAPIe's thread local implementation is
broken. Out of 100 requests, I got 77 id clashes. I ran a similar test
against isapi-wsgi and never got an id clash. Similarly, when running
in a native Python threaded WSGI server, I did not get any id clashes.

You can read a little bit more about how I became aware of this here:

http://groups.google.com/group/sqlalchemy/browse_thread/thread/fbca1399020f6a2e

A snippet of the log files from my thread test:

(4420) threadlocal did not exist, creating
(1580) threadlocal did not exist, creating
(4196) threadlocal did not exist, creating
(3852) threadlocal did not exist, creating
(3852) threadlocal did not exist, creating
(1580) id (4196) not equal

Your help would be greatly appreciated.
