Hi,
couple of emulations use the stackgap_alloc() hack. This works OK
in practice.

I'm not sure if this does not cause for threads which
share virtual memory structures and run independantly. If threads
share stack gap memory and a thread blocks, other thread might
overwrite the thread's structures, leading to problems.

Is the stack gap memory shared for FORK_SHAREVM ? If yes, is it really
a problem, or it's actually not possible to cause any problems ?
