[Openmcl-devel] Profiling using Shark

The good news is that ccl:library;chud-metering.lisp should already
know how to write spatch files for Shark, and that it seems to have
been conditionalized for x86-64 and ppc64.

The bad news is that - even though CHUD's release notes have declared
it to be 64-bit aware for the last year or so - the libraries used
to control profiling from an application are still only available
in 32-bit versions.  (This was true as of a few months ago;
I haven't checked to see if more recent versions are available
and if they address the issue.)

I don't know if Shark understand 64-bit spatch files, or if
the syntax of the spatch files generated by the function in
chud-metering.lisp matches its expectations.
