Background sweep and background free contend for the same jemalloc locks. They shouldn't run concurrently.

This should reduce lock contention on the jemalloc locks but it also makes
it easier to manage jemalloc state in the next patch.

I happened to notice this in [sp3] bug list. Does the patch improve performance or should this bug be closed as wontfix?

I don't remember if it changed performance. I do remember that it also helps one of the other bugs that had a better chance of improving performance. Leave it open, I'll get back to it but if you want remove the [sp3].
