May I suggest to introduce dedicated post-run hooks like

ess-R-post-run-hook, ess-SAS-post-run-hook etc.

and execute them just before the exit of "R","SAS" etc. functions.

Then users and packages designed with R in mind can use the R-post-run-hook
to inject the code and not damage the sensitive core code which is installed
directly in the "R" function.

Ess-post-run-hook is just too generic for this purpose and is not executed
(opposite to what the name suggests) at the very end of the process startup.

Will be really glad to see ess-tracebug as part of ESS. It will
probably take some time though. First, it's not feature complete
yet. Second, integration will probably require a closer look form an ESS
core, since I am redefining some fundamental pieces (such as process filters
and ess-command). Also XEmacs is pending because it seems not to support the
essential process-plist functionality yet.
