Please try again with the "-m"-related changes dsmith just checked in.

It's not the caching per se that's the problem, but that the default
module name (stap_<getpid>) is reasonably unique but hard to express
with "-m".

Martin pointed out that load-time module renaming is an option too
(see "modprobe -o NAME MODULE").  A good solution could be to do this
automatically at staprun time.
