Comment #17 on issue 3976 by [email protected]: OOM crash caused by GC not keeping up with fragmentation
https://code.google.com/p/v8/issues/detail?id=3976

regress-3976 exceeds handle count in some revisions. E.g.:
http://build.chromium.org/p/client.v8/builders/V8%20GC%20Stress%20-%203/builds/3896

Repro:

git checkout 7142b0d211b732e1c119fded80f43fbbd9cea0f8
