I've had an implementation put together from examples in various sources
for nearly a decade for the real ksh-8 and it works just fine with
pdksh too (somewhat more sophisticated than the ones supplied for Ash
(/bin/sh), including a showd and dirs too). Only 110 lines without
comments, and only adds about 20KB to the VSZ of /bin/ksh when initially
loaded. Look for .kshdir in:
(note that other files in that collection are getting way out of date
compared to my current working environment -- I need to roll another
release of them I guess...)

"suspend" is a default alias in /bin/ksh too....

What about when you've got more than one shell in the same session? :-)
(Eg. when you su and want to come back temporarlily to your login shell)
Even with new windows (i.e. xterms) for new sessions I still like job
control in some situations, and controlling sub-shells is just another
part of that picture.
