maps should not be flushed on a COMM event, so that was a mistake. Given 
that what new information does an EXEC event provide? Same process id. A 
COMM event is generated on an exec, so the name change happens. Mappings 
are dropped prior to that - and there is no unmap event. That seems to 
be a missing piece. Maps are added which is handled by MMAP events. 
After that why is an exec event relevant?
