Sometimes two correlated exception traces are observed in the server log for the Neutron Server backed by NSX: RequestTimeout (The nsx request has timed out) and OperationalError (Lock wait timeout exceeded). This is generally described by Guru Salvatore Orlando as the, and I quote, the "infamous eventlet-mysql deadlock". This patch tries to address the issue by adding a cooperative yield in the nsx client code (it’s a good idea to call sleep(0) occasionally in any case) and also by avoiding the unnecessary spawning of another Greenthread within a call that is already executed in Greenthred itself.
