[Opensim-users] Random OS console freeze on login; OS 0.7.2 Master

[Justin Clark-Casey]

Inspection of the EventQueueGetModule revealed some places where we weren't locking a client queue properly to protect 
against competing threads.

I improved this in git master 839c1cd.  This might help.  If not, please could you open a new mantis and put this 
information in there.

Thanks Chris!
