Subject: Don't wake up /sleep threads in think() anymore
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=141caf1d5b642bab826e2e8a7ab043b8c4928250

Don't wake up /sleep threads in think() anymore

When entering and exiting from think() we don't need any special
wake up / sleeping code because we want available threads to keep
sleeping.

No functional change.
