Thanks for the patch.

I observed that if the API is taking a nap in between slot sync cycles
and a promotion is triggered during that time, the promotion has to
wait for the entire nap period to finish before slot-sync stops and
the process can continue. There should be a mechanism to wake up the
backend so the API can exit early once stopSignaled is set. How about
doing SetLatch for the process doing synchronization in
ShutDownSlotSync()?

thanks
Shveta
