File tests/miscTests.py
Line 507:         """
Line 508:         try:
Line 509:             with tempfile.NamedTemporaryFile() as src:
Line 510:                 os.unlink(src.name)
Line 511:                 os.mkfifo(src.name)
what is writing to this fifo? we both no that this unlink/mkfifo pair is 
raceful, and that the unlink makes the with-as-src statement a bit pointless.

Maybe reading from /dev/fd/2 would be a bit simpler?
