[Zope-Coders] Zope 2 HEAD hanging on Linux

[Chris Withers]

Hi,

You may have noticed there haven't been any Linux test emails for the last 
couple of days. It appears that The Zope 2 HEAD tests are hanging again :-(

Worse still, if I run them by hand on the same checkout, they appear to go fine :-((

If it's any help, a pstree looks like this for the hung stuff:

cron---cron-+-sendmail
             `-sh---python-+-python---2*[python]
                           `-python2.2-+-python2.2---6*[python2.2]
                                       `-python2.2

None of them shows up on top when sorting by CPU usage, so they must all be at 
0%. When sorting by memory usage, they all show up, but I get a lot more python 
entries than are showing up in the pstree output:

I'm kinda stumped as to how to debug this now, any ideas?

cheers,
