Done that. It's very interesting to do this while zope is starting up.
It seems the last 10 of my seconds zope is in a tight loop calling time()
and doing nothing else.

If I do strace -p on a thread that processes an HTTP request, strace
immediately exits without displaying anything (maybe because strace
does not support threads?)

I'll try upgrading strace in a moment.

Note: this is a RedHat 7.0 system.
