I'm not familiar with valgrind, but from what little I can tell it
does slow things down but isn't intended for that purpose and there's
not really a controlled amount of slow-down?  Also it looks like it
needs to be involved when you compile stuff and I don't want to have
to recompile bash ... am I correct about this?  Please let me know,
