Maybe that's enough In terms of the MSYS/Cygwin style of fork emulation, large memory allocations shouldn't pose any real problem, but they will be slow as the fork emulation has to manually replicate the state of the parent in the child and this means copying memory extents. (Yes, horribly ugly, no doubt about it, but it allows for porting.) This emulation code is sensitive enough that the Cygwin list has begun to maintain a list of software whose hooks/interference can cause Cygwin apps to fail: <http://cygwin.com/ml/cygwin-talk/2007-q3/msg00174.html>. Since MSYS is derived from the same code I see no reason why the list wouldn't also implicate potential problems with binaries linked to the MSYS runtime.

I think you may be stuck on the shell though -- I don't know of any ports of bash that aren't MSYS or Cygwin based. However I do think there's a native port of zsh out there by the GnuWin32 project, which when renamed as just "/bin/sh" might be suitable, but only if these scripts don't use bash-isms. I have not tried this zsh myself and speed/compatibility wise I'm not sure it's up to snuff.
