Are you sure that moving to low priority xcalls is the way to go? You

Curiously, while I could reproduce the crash before this commit, I am
unable to reproduce it in any testing without the actual ucode update
happening - and I can not spot a bug in the xcall code that tries to make
sure the number of cpus that did run the callback is == the expected count
before returning.
This clearly needs full analyzis.
