Typically the output is from some process that has a lot of overhead 
that I don't want to spawn multiple times. 

E.g. running system_profiler on a G4 Mac grinds the CPU for a few seconds, 
and it outputs blocks of text, so I grab the block, stuff it into a 
variable and then I can chop it into useful pieces without having to 
run the command again. 

I could do this with a temporary file, but I avoid temp files as much as 
possible.
