+Don't attempt to wrap GreenPipes in GreenPipe
+
+If the os module is monkeypatched, Python's standard subprocess module
+will return greenio.GreenPipe instances for Popen objects' stdin, stdout,
+and stderr attributes. However, eventlet.green.subprocess tries to wrap
+these attributes in another greenio.GreenPipe, which GreenPipe refuses.
