Log Message:
-----------
bash, add support for the loadable builtin 'sleep'.  This is useful for scripts that contain a wait loop, ex.
--
while test_something; do
  do_something
  sleep 1
done
--
since by default sleep is not a builtin to bash, a new /bin/sleep process is called every second.  We can now call
--
enable -f /usr/lib/bash/sleep sleep
--
whenever this is important, for example with AIF plugin helper scripts.
