That is all true. I was of the opinion that it was not quite so
dangerous because this method worked fine most of the time for
shells. But I agree now - we should be careful, and abide by higher

And I think the suggestion I made in the email I sent just before this,
to use a new kind of magic path, and thereby reuse all the process-file
infrastructure, is the best way to be careful in this matter.

Only the programs that can and should be run remotely, use process-file;
and I contend that those programs are exactly and exclusively the things
we want to run inside a custom environment.
