-----------------------------------

I don't understand what exactly that unit that would be testing.

> Typically the symptom with jenkins is strange socket failures (because sockets are files
too).
> On my machine though i got the nice too many open files from lucene because it just happened
to fail that way.
> In addition to holding thousands of open files, this test creates 90 *megabytes* of logging
output!
> Can we tone down the test? I havent looked at all: but it doesn't seem necessary to have
huge numbers of cores/indexes to test the functionality, we should be able to do this with
relatively small numbers. 
> Additionally i dont think its good to use random merge/IW buffering parameters here,
we should set ones that won't make tons of files, force the use of compound file format, etc.
> The massive amounts of logging should be addressed too.
