---------------------------------------

@Oleg: I'm fine with delaying this fix till after 4.1.2. I think it's going to take longer than I thought originally.

> Currently, the ThreadSafeClientConnManager reuses persistent connections in a round-robin fashion: when the connection is checked back into the pool, it is added to a queue of available connections for later use. This has the perhaps unintended effect that the client may keep open more connections than needed, because the "last used" time keeps getting updated and none of the connections can get reclaimed via closeIdleConnections().
> Exchanging the queue (FIFO) for a stack (LIFO) would result in extra connections actually becoming idle for long enough to be reclaimed.
> I have a working patch for this; just need to get my act together to get it in.
