The problem is that the file rate limit is not hit because work is done
elsewhere. The rate can limit the bandwidth used and makes QEMU aware
that socket operations may block (because that's what the buffered file
freeze/unfreeze logic does); but it cannot be used to limit the _time_
spent in the migration code.
