This is insufficient as a programmatic restart.  Imported packages are not
cleanly re-imported.  See the caveats surrounding reload() for instance.

%reset seems to be a bit worse though, as far as I can tell it does NOT reload()
modules (does not recompile them).  What would be required to make %reset see
source changes on imported modules?

So maybe it wasn't a stupid question, as this functionality doesn't exist...
