Ooo, good question. It looks like the interweb is mixed in opinions on this;
select() works on sockets, but I don't know if Windows pipes to a subprocess
are considered sockets, and I don't know if fcntl will work but I'm not
optimistic.

So, it may be that your approach is best and we'll have to expect
num-test-shells=1 to potentially wedge (and maybe I can rip the non-blocking
code out of the mac port).

We should at least check to make sure that you didn't do anything that causes
num-test-shells=1 to outright break in the normal (non-wedging) case.

There's a PEP out for better non-blocking communication, but I'm not gonna hold
my breath for that.
