sorry.
3.6 is synchronous idles when we use tj's replacement for patch2.
and maybe_rebind_manager() don't wait for idles rebind. so it can't go to 3.6.

Choice1: also push Patch 2(async idle rebinding) to 3.6? thus patch 4
can goto 3.6 too.
Choice2: add workaroud and make patch4 and make it go to 3.6. (add some code.)

Thanks.
