@joshelser I have been thinking about performance w.r.t these changes.
Looking over all of the changes, they are all in close methods which are called
per block and not per key/value. So given that they are called less
frequently, I suspect it would not cause performance problems. Also, in the
normal case everything should be single threaded, so I am thinking we should
not see performance problems caused by threads waiting on each other in the
normal case. But perf testing would still be nice if someone has the time.
