Is this supposed to work rsp. does this work for anybody?Cygwin has known bugs with named pipes, and they are so severe that autotest parallel tests are known to fail on that platform. There's nothing autoconf can do about it until cygwin's pipe implementation is fixed.
Unless you can find a quickie shell test that validates whether the named pipe implementation is buggy and can thus skip parallel testing on cygwin in the first place (I haven't yet found such a test that rules out cygwin but without hanging). We already have other quickie tests, like whether set -m works, whether mkfifo works and whether trap ... STOP works; but the problem is all three of those work on cygwin.
