[Midnightbsd-cvs] src: src/bin: Add pwait(1), a utility to wait before running a process.

[laffer1 at midnightbsd.org]

Log Message:
-----------
Add pwait(1), a utility to wait before running a process.  

This is similar to the utility from Solaris 8+.  Great for things like rc.subr's wait for pids or interactive use.

Also clarify size contraints with uuidgen(1).

Obtained from: FreeBSD
