> I tried GetProcessId again and it works. Not sure what happened when I
tried it before, but I think I might have messed up the calling convention
by not defining _WINNT_VER before including windows.h (I noticed this time
when I was testing GetProcessId in runProcess.c that I got a warning that
it was GetProcessId's sig was not defined if I did not define _WINNT_VER).

I took a quick look, and the changes look fine - much easier to review
this version without the changes to `ProcessHandle`. When you've reached
a fixed point with the patch I'll push it in.
