Largely addressed by:

Could you confirm what's yet not fixed by that? I suspect
only bit not addressed by that patch is the phantom read reported
on x86 when the program writes the same memory as was already there.
I don't have better ideas at this moment on how to fix the intel
phantom read case other than parsing the instruction that trapped
and checking if it was reading or writing memory. I'm inclined
to close this PR, and open a new one specifically for that case,
maybe also adding a test for that to the new watch-read.exp
file I just added, and XFAILing it. WDYT? Any better ideas?
