> If a RegionServer host is already heavily loaded* then it might not be best to accept more work in the form of coprocessor invocations. This could generalize to all RPC work, perhaps as part of a broader admission control initiative, but I think it makes sense to start small in an obvious place.
> *: We could use % CPU utilization or the UNIX 1min or 5min load average to determine this, and provide an option for choosing between those alternatives.
