Erm... I doubt it's "just 10 lines" - you need a bit more code. Beyond
that we would have to maintain two codelines, including for the
following upcoming changes:
- Adding "-s" for alternative signal handling
- Use of |sched_yield()| for zero values (based on empirical testing for
the builtin command version)
- GNU sleep-style postfix operators for { seconds, minutes, hours, days,
weeks, months, years }
Some of this stuff is already implemented in the current AST/ksh93
"sleep" builtin and the other things are added with one of the next two
ksh93-integration updates. But we keep /usr/bin/sleep as standalone
utilty with no codesharing between /usr/bin/sleep and the AST/ksh93
version of "sleep" we double the engineering time for this...
