That won't work, as too many parts of the system ignore the aliases.

Yes, something like that should work.  You can set up your own 
implementation of grep, like this:

#! /bin/sh
exec valgrind --log-file=foo /full/path/to/actual/grep "$@"

in a shell script called 'grep', in a different directory, and prepand 
that directory to your PATH.

Perhaps Jim has a better way to do it, though -- he's more of a valgrind 
wizard than I.
