"The parameter is incorrect" is a Windows system error message.
Apparently, there is something wrong with one of the parameters
we pass to CreateProcessW. I don't have my dev computer with me
now, but my first guess would be the command line or one of the
pipe handles. I'll check it out.

Usually, when such things have happened to me, it is because I've
forgotten to flush a stream. That doesn't seem to be the case
here, though, since you close pipes.stdin manually. Do you know
where the program gets stuck? I guess it is the read loop, but
if you could verify that, it would be great.
