* WP: June 2009. Globally only permit a single ACT-USER command to be outstanding at once. Why?
* Thanks to OMEA stupidity, if the NE is set to use OMEA for radius authentication then we hit
* a bug with OMEA. OMEA can only process a single RADIUS login request at a time, if we have 10
* threads all trying to login to NEs after a restart we'll have 10 outstanding RADIUS requests
* and most/all will fail and mess us up big time. We used to globally restrict the number of
* worker threads to just 1, but that slows down the rest of DRAC, especially if we have > 1 NE
* that are unreachable, we'll spend too much time trying to reconnect to the dead NEs. Instead
* we lock just the ACT-USER phase.
