Thanks.  We are trying to close a handle on which the reader thread
already started reading, so the OS doesn't let us delete it.

This whole pipe-process stuff is flaky on MS-Windows.  Patches to fix
it are welcome.

I installed on the master branch a fix which hopefully won't break
anything.  Please see if it fixes your problem.

Thanks.
