Going by instances of remote_file delete in the testsuite,
it's at least semi-standard to do so. It certainly reduces
the chances of confusion for any functionality that is based
on searching for a matching file to load/process.

I could go for that. The existing deletions seem to be in a variety
of styles, and it would be useful to have standard failure handling
and such.
