Have you actually tested sh's wait command?  It seems to wait on PIDs
just fine for me:

$ sleep 20 & jobs
[1] 98000                     sleep 20
$ date ; wait 98000 ; date
Wed Jan 20 15:41:59 CST 1999
Wed Jan 20 15:42:14 CST 1999
[1] 98000 Exit 0              sleep 20
$

took me 5 seconds to type the 'wait' comandline.

There cannot be a /usr/bin/wait, since the wait() syscall only lets a
process wait on its children.  It has to be a shell builtin.
