#144 OpenSLP 2.0.0.0 rare exception in SLPOpen on Windows platform

[Evgeny]

I found that on some rare cases (probably it depends on machine load) on Windows 7 x64 environment there unhandled exception occurs during slp.dll usage. I discovered that exception appears inside SLPOpen:

if ((res = SLPOpen(NULL, SLP_FALSE, &slp)) == SLP_OK)

and thrown at line 214 of libslp_handle.c:

handle->langtaglen = strlen(pcLang); (Access violation exception)

Like in ticket #145 I found that exception appears actually one line earlier.

Seems to me problem related to internal implementation of Win32 mutexes (CriticalSection) and will try to substitute threading implementation in OpenSLP project to pthread_win32 lib which can handle some abnormal behavior of WinAPI functions...
