Hi
I'm not an expert on this. But when compiled with --with-ipctype=doors
it will use pthreads. Also, the auth_shadow.c contains #ifdef _REENTRANT
directives, suggesting possible multi-threaded use.
So someone (perhaps upstream) should make sure the code is safe to use
in all configurations.
CU,
Arno
