Define "funky shell". Does it have to be straight up plain sh? Can it 
use csh or tcsh syntax? Does bash count as 'funky'?

Do you mean "manually created temp files"? because some of the different 
ways of doing process substitution and redirection will automatically 
create temp files for you in the background and fail on an unwritable 
filesystem.
