[evlatests] Initialization problem

[Walter Brisken]

Quick question for everyone on the list.  Does anyone have any examples of 
the initialization problem occuring in non-fast-switching cases?  My 
immediate guess is that fast switching doesn't get a flag after source 
change because of the way it shares infrastructure with mosaicing that 
doesn't want that flag.

For fast switching scans, I can perhaps understand missing the source 
change flag, but I am really surprised that an off-source flag doesn't 
catch these since a flag is generated if the antenna is off source for any 
part of an integration.
