Hmm, currently we just use the `shell' command which defaults to the
user's defined shell.  I would have to investigate as to how to
explicitly specify a particular shell to run, but I certainly do see
your point that there are times when an explicit shell environment would
be desirable.

I'll create a TODO to reflect this need.

Yes, I agree that this should be implemented, patches are welcome :)

Thanks for the very useful feedback, hopefully we'll be able to make
some progress in these areas soon.
