Not just in bash, but in cygwin in general.  Named pipes are still an
incomplete implementation, and until patches are written to get it
working more like posix, you can't expect them to work reliably.

Sorry, I don't have any.  Autoconf is another client that would love to
use named pipes (for parallel testsuites), but which can't do so until
cygwin's implementation is completed.
