(lack of) Parallel testing on Win32

What gets in the way of running tests in parallel on Win32?

Was it that

a: one can't select on a pipe in Win32
b: whilst one can select on a socketpair on Win32, if the reading process
   terminates before the writing process reads the pipe to EOF, data in
   transit is silently lost

?

[citations needed, obviously. I think I had them but I've lost them. Silly me]

With the result being that there's no way to have 2+ subprocesses running, and
reliably read their output as and when it arrives.
