I've noticed this too, and it seems like a good idea to me.

If the RExpression actor put these files into the provenance DB, then they 1)
wouldn't need to be on disk to be cleaned up, and 2) would be part of kar run
archives when they are saved.  Deleting runs would then also delete the
provenance record, which is enabled with a UI, so it would be more intuitive
for users.  Do we already do this with RExpression to enable including them in
reports?  Can we eliminate the temporary storage altogether, or just delete the
cached files from disk as Oliver indicates?  Does ImageJ and other actors use
the disk version to display the files, and if so, could it be made to use the
provenance db version?

In general I think its better to write results to provenance and then be able
to access those results from provenance.  This centralizes result managment,
and avoids the messy actor-by-actor management of outputs.  Thoughts?
