That seems crazy. The chdir should be happening on the child side of the
fork (and looking at the code, it seems to be the case). And on the
Windows side, without fork, it's an option to the spawn call, which
makes sense.

Yeah, that would push it after the exec. I just don't understand why
that would be necessary.
