assignment - is master beeing a watchdog useful?

See comments in HBASE-7247: the master checks the time spent by the
regionserver, and assign it to another if it takes too long. It adds
complexity.

from Stack: "I'm currently of the opinion that this expensive facility of
master failing an open because it has been taking too long on a particular
regionserver has been of no use – worse, it has only caused headache – but
I may be just not remembering and others out on dev list will have better
recall than I."

So, opinions & memories are more than welcome.
Removing this feature would be a huge simplification!

Cheers,

Nicolas
