Description of problem:
Strange traceback in ceilometer/central.log - 
2015-11-19 08:08:48.844 25809 ERROR ceilometer.hardware.pollsters.generic ;RuntimeError: Second simultaneous write on fileno 21 detected.  Unless you really know what you're doing, make sure that only one greenthread can write any particular socket.  Consider using a pools.Pool. If you do know what you're doing and want to disable this error, call eventlet.debug.hub_prevent_multiple_readers(False) - MY THREAD=<built-in method switch of GreenThread object at 0x2da5050>; THAT THREAD=FdListener('write', 21, <built-in method switch of GreenThread object at 0x2da50f0>, <built-in method throw of GreenThread object at 0x2da50f0>)

Looks like some race condition bug cuz after restart it wasn't reproduced.
