[Mesa-dev] Is Mesa on win32 thread safe?

Hi,

Is Mesa 8.0 implementation on windows thread safe?
I have some test code that is doing rendering in parallel threads using
debug build of opengl32.dll and it is crashing in debug_free on list_del
operation.

The implementation of u_double_list.h does not seem to be thread safe, so I
believe if concurrent debug_free/debug_malloc happen it can cause crashes.
Is it possible or is there proper locking somewhere up in the calling stack?

Thanks,
Juraj
