Subject: Add a couple of asserts to late join
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=193a7ae35be740f8ff78e103fc605557a503ebbe

Add a couple of asserts to late join

Document and clarify that we cannot rejoin on ourselves
and that we never late join if we are master and all
slaves have finished, inded in this case we exit idle_loop.

No functional change.
