Description
After the December changes in condition_variable, various programs started to freezes randomly. About 10-15 freezes per day - one of the open windows simply stops refreshing (Tracker, Deskbar, Telegram, Pe and others). In rare cases, there is a complete system freeze. If I revert changes in condition_variables.h and condition_variables.cpp to 1728b8c7778d24e0daed7468f33dadf2f48c15ad commit, the problem disappears completely.

Possible patch: https://review.haiku-os.org/c/haiku/+/4890
Uptime is about 8 hours, no freezes. This patch seems to fix my problem.

Merged (with some minor modifications to remove now-unneeded atomics) in hrev55841.
Please retrieve a KDL backtrace of a few of the stuck threads (i.e. drop to KDL, run "bt" on a few threads, exit KDL, upload syslog.) I think nephele may have seen some similar symptoms though so maybe you are not the only one who has experienced this. Permanent hangs are very weird, that likely implies a defect in the thread blocking code...
