[Zope-dev] Segfault and Deadlock

Native POSIX Thread Library.

However, i dont know enough about NPTL. Only that it caused us some
grief when we migrated applications from RedHat-7.3 to RedHat-9 (we
had to set LD_ASSUME_KERNEL=2.4.1 for some applications [including
oracle] to work).

Yes, i think it is more a python problem than a zope problem. But it
bites the Zope server on a linux system w/o NPTL. Maybe we have more
luck this time...
