  I have core dumps with Paster (only with Paster) in some similar
  cases. I think it is because of the threads-o-clever-on-demand
  algorithm of Paster that mess up with other Zope C components.

  I have not such problem with mod_wsgi.

  For the mess-up request part, well it is the Zope 3 publisher who
  doesn't handle properly that interruption. Good luck if you want to
  fix it.
