By the way, I just realized something that wasn't initially obvious
to me, and documented it in the futex(2) man page:
Note: for FUTEX_WAIT, timeout is interpreted as a
relative value. This differs from other futex oper‐
ations, where timeout is interpreted as an absolute
value. To obtain the equivalent of FUTEX_WAIT with
an absolute timeout, employ FUTEX_WAIT_BITSET with
val3 specified as FUTEX_BITSET_MATCH_ANY.
Okay?
Yes.
Thanks, Thomas.
Cheers,
