revisit segments.gen sleeping

                 Key: LUCENE-3605
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Robert Muir

in LUCENE-3601, i worked up a change where we intentionally crash() all un-fsynced files 
in tests to ensure that we are calling sync on files when we should.

I think this would be nice to do always (and with some fixes all tests pass).

But this is super-slow sometimes because when we corrupt the unsynced segments.gen, it causes to take 500ms each time (and in checkindex for some reason we do this twice, which
seems wrong).

I can workaround this for now for tests (just do a partial crash that avoids corrupting the
but I wanted to create this issue for discussion about the sleeping/non-fsyncing of segments.gen,
because i guess its possible someone could hit this slowness.
