Description

currently the fact that MockDirectoryWrapper has throttlers and such that sleep, combined with the fact this test interrupts, makes a good test for exception handling.

The problem is this is really crappy to debug: things dont reproduce, you have to use hundreds or thousands of iterations, etc etc.

I think it would be better if we made it possible for MockIndexInput to throw random exceptions like MockIndexOutput and had a single threaded test that just threw random exceptions? This way it would reproduce...
