Description

Since the new multiThreaded search feature landed, I see a new test
failure involving "RejectedExecutionException" being thrown link.

It is thrown at a low level in Lucene building TermStates
concurrently. I doubt the problem is specific to that test
(TestRealTimeGet) but that test might induce more activity than most
tests, thus crossing some thresholds like the queue size – apparently
1000.

*I don't think we should be throwing a RejectedExecutionException
when running a Search query*
