This version of the patch looks fairly sane in terms of how it connects
to the rest of the code; but I'm unqualified to comment on the
Windows-specific code.

One thought is maybe the call point should be in startup_hacks() rather
than the main line of main()?  I'm not terribly set on it if you don't
like that.

Also, I notice that the comment for startup_hacks() claims that it isn't
executed in subprocesses, which is evidently an obsolete statement ---
that should get cleaned up independently of this.
