Log message:
libc, librthread: _twait: subtraction is not comparison
Compare the current time with the absolute timeout before computing
the relative timeout to avoid arithmetic overflow. Fixes a bug where
large negative absolute timeouts are subtracted into large positive
relative timeouts and incorrectly cause the caller to block.
While here, use timespeccmp(3) and timespecsub(3) to simplify the
code.
