That can be dealt with, because AttachConsole reports back whether it
did manage to attach, so if it doesn't, one can then call AllocConsole
and ShowWindowAsync.

But on 64-bit Windows 7 there were some bizarre problems, where it
just wouldn't attach or it would completely block the parent's
console. See http://code.google.com/p/mintty/issues/detail?id=3D83

Ah, seems I jumped to conclusions from this, although it does sound
like it might address the problems above:

2009/5/16 Corinna Vinschen:
"That's not a workaround for the problem with consoles popping up, but a
workaround for a W7 x64 specific problem.  There's a bug in the W7 x64
console code (which appears to be mostly rewritten in W7 anyway) which
breaks DLL initialization in child processes which have no copy of the
original console handles from console startup anymore.  This bug has been
reported upstream and is marked as being resolved, which hopefully
means it will be fixed in the final W7 release."
