HR fix review: #213640 - repeated profiling doesn't work

Description: http://netbeans.org/bugzilla/show_bug.cgi?id=213640

Repeated profiling does not work because the state of underlying GF 
common code base is not properly updated to reflect that instance has 
been started in profile mode.

Risk assessment: Should be safe. We are using polling thread to update 
state.
