bent, is this anything to be worried about?

When I run e10s xpcshell tests in /netwerk/test/unit_ipc, bloatview reports that they're leaking memory:

== BloatView: ALL (cumulative) LEAK STATISTICS, default process 30311

                      Per-Inst  Leaked   Total      Rem

219 nsTArray_base            8     144     809     18

Most likely suspect seems to be ContentParent.

I did a quick, partial regression search--this is not happening on the beta branch as of today (so Firefox 22), but is happening on aurora/nightly.

We should fix it, but since it's just test leaks I wouldn't panic :)
