The problem is, apparently the thing gets in a really tight loop - one
threads blocks the rest of Zope, so it is quite hard to use these
tools (especially not when the whole thing is not - yet - reproducable,
sometimes it happens in an hour, sometimes after 12 hours; a bit hard
to keep staring at the screen for 12 hours :-)).

As a bit of an act of despair, I'm currently logging Zope's CPU usage
every 5 seconds in a log file, hopefully I can match a rise in CPU time
with some request in the server logs.
