I can only confirm this. We just saw that unfortunate deadlock again in real
application (something to be shipped in products). We ran into it before, but
this time we finally realized that it's not due to an outdated glibc but rather
a still unfixed bug.

Our applications consist of dozens of real-time threads at different prio
levels and practically can't be reworked to avoid cond variables in RT threads.
So we really need a solution, and that preferably without having to carry our
own patched glibc versions.

Thanks,
Jan
