-------------------------------
Having a timeout configurable is always good. :-)
> Protect coprocessor from exhausting mem or cpu of region server

> HBase coprocessor may run long, consuming lots of mem and/or cpu on region
> server for whatever reason. When this happens, the client side RPC timeout,
> but the server side is leftover to run, continue occupying the resource.
> Need a mechanism to stop the server side in such scenario. Either by a
> timeout, or by mem consumption, or both.
