while this would work, it wouldn't be as efficient, for example compare
amount of code that implements reentrant mutexes on win32 with construct
that is written for pthreads (and which would have to be fully executed if
pthread emulation would be chosen). threading part of libxml is sufficiently
small and separated to be implemented natively without any emulation, imo
anyway.
