I think thats fine for now, but I'm not convinced there is no problem
at all. However, its not obvious the problem is us, either.
Its easy to see this OOM is related to G1 garbage collector.
This test has failed 3 times in the past couple days (before it never
failed: i suspect packed ints changes sent it over the edge).

https://builds.apache.org/job/Lucene-Solr-tests-only-trunk-java7/2723/
All 3 cases are java 7, and all 3 cases uses -XX:+UseG1GC. (Uwe turned
on GC randomization at lucene revolution)

Aaahhh... I thought G1 will start causing issues at some point. Good
catch, Robert.

Aha! Nice sleuthing :)
So maybe this means G1 isn't as good when heap is limited...
Can we somehow detect / pass property to the JVM when G1 is in use?
Then we can scope down the "ignore OOME" I committed to only when G1
is in use...
