[Zope-DB] Getting 500's and 503's from Zope + Firebird

I tried multithreaded python gvib stress test found on 
http://clientes.netvisao.pt/luiforra/ib/stress.py
and it crashes with

Program received signal SIGSEGV, Segmentation fault.
0x401f943f in THD_restore_specific () from /usr/lib/libgds.so

(output from gdb).
