I'm working on Win32 (WinXP pro SP3).
I tested a fresh V1.0 project, and I don't get the warnings. I do see,
though that it always is another thread handling incoming threads in a
'round-robin' fashion, but I personally don't see any problem with that.
Apparently, in my existing project, the threads keep a connection to the
ZODB open for some reason, even though the request is completely handled. If
I hit a breakpoint there always is only 1 thread alive, all the others are
sleeping (I'm the only user, remember).
I didn't have this behaviour before, and the main changes I recently did are
upgrade to V1.0 and implement LDAP authentication using ldappas and
ldapgroups(a package I wrote myself), so perhaps there is something in
ldapgroups that causes it...

How can I find out when a connection is opened/closed, or how many
connections are open?
