Shai Erera commented on LUCENE-3195:
------------------------------------
That's a great idea !
bq. and it should throw exception on openInput
and createOutput too?
bq. we should take a good default value
Let's just start w/ 1024? I doubt our tests need to open that many anyway, and
it's, I think, low enough to fit any OS?
Also, and this can be added in future iterations, I think it'd be good if the
exception includes a list of all test classes + count of open files, to make it
easier to spot offending classes.
Hmmm ... now that I think of it, if our tests are run in different JVMs, we
will fail to faithfully track the number of open file handles (I mean the
*true* number)? In that case, we might want to lower the value to whatever we
think a single JVM should allocate ... which gets tricky.
