Reading over this old script again, I'd take away the following
observations:

- process argument fetching routines would be welcome the tapset library
- a syntax to initialize a systemtap array would be useful - both at
  compile time ("global array[maxsize] = [idx]=value, [idx2]=value2")
  and at run time (module option string "[idx]=value, ...")
- some systemtap policies/libraries have become more favourable to this
  kind of script since January.
- a new script that exploits these hypothetical features would be much
  more compact and may still make the shell script wrapping unnecessary
