Colin Patrick McCabe commented on HTRACE-302:
---------------------------------------------
* Add test hooks to the golang client and HRPC server, so that we can inject
faults during unit testing
* Add configurable I/O timeouts to HRPC, so that the server can't get blocked
indefinitely by really slow clients. Default I/O timeout is a minute.
* Add a configurable maximum number of HRPC handlers
* Add {{TestHrpcAdmissionsControl}} and {{TestHrpcIoTimeout}}
* {{MiniHTraced#Close}} must shut down the HRPC server and block until its
goroutines are done.

> htraced: Add admissions control to HRPC to limit the number of incoming
> messages. This is important because if we bring in too many messages at
> once, we'll end up using a huge (potentially unbounded) amount of memory when
> we deserialize them. Meanwhile, most messages can't be processed faster than
> the datastore can handle them.
