Description (partial)

DCM crashes right out of the box!

the problem may occur (may because i cant reproduce it) because the Mux thread is started BEFORE Measure::Init() and AlarmTrigger::Initialize(). 
Those 2 last functions will insert Operations in the OperationContainer of the DevCtrl module, which is fine unless Mux core thread process a NotifyLicenseServerReadyMsg (HandleMB started) right at the same time.
In this very rare situation a sort operation is done by mux and inserts are done by root.

stl sort and insert are not thread safe and it could well be the issue. anyway code must be made more robust (starting the mux AFTER the measure and alarm operation registering)
