 is reproduceable, seems to happen when hang-detection is triggered twice at startup.

to easy reproduce, set HangTimeout=1 and rm ~/.spring/cache/ArchiveCache.lua

 Some info

Sim thread hangs in SDL_Delay()
Main thread hangs in SDL_GL_SwapBuffers()
Hang Detector is making a trace for the main thread, and hangs in GlobalAlloc

Probable conclusion: SDL uses GlobalAlloc as well, and thus this is an allocator related deadlock. Possible solution would be to preallocate all, try another allocator such as VirtualAlloc or HeapAlloc, or make an allocation attempt in a thread and abort the trace attempt if it does not return within reasonable time.
