<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">NonMoving: Don't do major GC if one is already running

Previously we would perform a preparatory moving collection, resulting

in many things being added to the mark queue. When we finished with this

we would realize in nonmovingCollect that there was already a collection

running, in which case we would simply not run the nonmoving collector.

However, it was very easy to end up in a "treadmilling" situation: all

subsequent GC following the first failed major GC would be scheduled as

major GCs. Consequently we would continuously feed the concurrent

collector with more mark queue entries and it would never finish.

This patch aborts the major collection far earlier, meaning that we

avoid adding nonmoving objects to the mark queue and allowing the

concurrent collector to finish.
