I think you'll have to use the same techniques you would use in plain
C. See for example: <http://stackoverflow.com/questions/1906228>.
However, your Lisp's memory management might interfere. For instance,
Valgrind and SBCL don't get along at all.

You might have better luck with tools that only instrument
malloc()/free() if your implementation doesn't use malloc() to
allocate Lisp memory, e.g. SBCL.

There's CL:ROOM, and most Lisps have memory profilers. (I'm not aware
of any such profilers including foreign memory usage, unfortunately.)

You might get better informed answers if you ask this question on your
Lisp's mailing list.

HTH.
