This causes thread related failures on my Debian unstable system using
glibc 2.3.2 (nptl not enabled). For example his is Agent after calling
WSAAsyncGetHostByName:

| Unhandled exception: page fault on read access to 0xdbdbdbe3 in 32-bit code (0x402ddfaa).
| In 32-bit mode.

(it crashes inside gethostbyname(), without obvious reason).

Debugging hints are most welcome.

I think this should be fixed in current CVS, please give it a try and
let me know how it works.

Yes that worked. First I thought that it created another problem, a
crash in ExitProcess(), but that stopped for no known reason.
