Joe Drew c77ce2595e Bug 490384 - Only evict unused cache entries when under memory pressure. r=vlad a=sdwilsh for push into CLOSED TREE
Prior to thise, when we were under memory pressure, we would remove every
entry from the cache, even ones that were currently held in memory due to
their use on e.g. a web page. Now we only remove things from the cache that
will actually free up memory, further fixing bug 466586.
