This test had a huge iteration count, was checking tons of stuff unnecessarily... I rewrote it to just compare against Java's PriorityQueue... but it turned out that lucene's PriorityQueue.remove(T) is implemented as a linear scan through all elements, with reference equality (which is surprising to say the least...). That's why this "cache" of ints needs to be here.
PQ.remove is only used from one place within Lucene... maybe we should drop this method entirely (or at least change == to .equals to be less surprising?).

I'll help with merging this branch out of conflicts: I'm not actually "fixing" anything in |

No worries, I'll handle the merge and conflicts. |

I'll merge this in. There's been work on speeding up tests on other branches and indeed - we can just tackle them individually, on need for this branch. |
