So far, two people have submitted patches to "fix" the "memory leak" in
icode_to_fcode() by having it free the bpf_insn array before returning a
pointer to it.  Add a comment to icode_to_fcode() explaining why this is
not a leak in icode_to_fcode(), it's a leak in their program, and
indicating how to fix the leak.
