   I already got segfaults myself with zope.component in Zope 2.11 when
   doing race conditions: two threads registering the same adapter at
   the same time. It corrupted Python memory leading to segfault few
   seconds after. Maybe somehow you have the same thing.

   I don't image writing a test for it, so I just adding a lock around
   all registration steps in the ZCA, and it worked fine.

   Best regards,

   Sylvain,
