Subject: [PATCH] When ram watch is open with a file open, and loading another
 rom, only keep the ram watch file open if all the domains are compatible,
 else close it, addresses #285.  There is arguably not a black and white
 expectation in this scenario but I think this is marginally more expected
 than exceptions and erroneous watch values
