+ In the event of CMonitor's call (via this class) to RProcess::Logon() completing its iStatus with 
+ KErrNoMemory, this AO will retry the logon a number of times, each time after an 
+ increased interval (up to a maximum). This is to ensure that if the low-memory 
+ condition is cyclical in nature, we won't be unwittingly synchronised to it.
