Rollup merge of #137731 - SparrowLii:waiter, r=nnethercote

Resume one waiter at once in deadlock handler

When multiple query loop errors occur in the code, only one waiter should be resumed at a time to avoid waking up multiple waiters at the same time and causing deadlock due to thread grabbing.

This fixes the UI failures in #132051
