wineserver crash during WineTest

[Francois Gouget]

So I did not have time to look into this yet but last wednesday 
wineserver started crashing during WineTest. So it's likely a patch in 
f65cfbfe9b20..f52b33c63064.

Apparently the crash happens around the time that the ntdll tests are 
running but of course all is fine when manually running 'cd 
dlls/ntdll/tests && make -j1 test'... but it does happen if I run 
./wine winetest.exe -c -t foo -m foo ntdll.

Is this a known issue?
