Thanks!  I'll look into those repos for a potential house for this.

I wrote the Python script because I thought the logic was too
complicated for bpftrace to handle.  I thought it only handled simple
scripts with simple logic, i.e. no recursion which this script uses.
If that isn't the case, I can certainly try it.
