 Ok, from the stack trace we can see the call to open64, which is
 hanging.  open is trying to open /var/run/zmd/zenevents which is a pipe.
 I do not know in what mode it is being opened, but there are no
 processes on the system trying to use the file.

+    This Mono process seems to be just fine in terms of waiting, so
+the question we have to find the answer to is: why is this process not
+waking up in WorkerThread to the incoming request, and at this point
+it is not clear that this is a Mono bug.
+    The bug seems like it can be reproduced, it would be great if you
+could reproduce that with an instrumented or debugging version of ZMD
+with proper Console.WriteLines sprinkled to find out what is happening.
+    The main loop is waiting as it should, but its not being woken up
