...perl takes less than twice the memory of bash.

I suppose it depends on the system and shell, but aren't shell processes often kept in shared memory, and so additional shell processes would take little or no additional memory? I remember reading on some man page that you usually may as well spawn another process rather than use 'exec' for this (among other) reason(s).
