GuestWriteWatchTrapReads takes all access to the pages of a range until
the resolver set with GuestWriteWatchSetReadTrapResolver has run for it.
A fault on a trapped page waits while the resolver runs on the watch's
own thread; host writes and GuestWriteWatchProtect run it first on the
calling thread. Collections keep trapped pages inaccessible, and
registering or unregistering memory drops its traps.
