I would do that too if I had any idea what you mean :)

Could you give me an example of what you mean by modifying the callback?
I like the idea of altering DB::sub
Since I have not clue what I'm doing, I tried deleting all the spreadsheet subs using: 

  
map {delete $DB::sub{$_}} grep {/spreadsheet/i} keys %DB::sub

[download]
The first time I ran after that, it saved me 10 seconds,
but that wasn't repeatable, and I'm pretty sure it had no effect at all.
because its way after all the subroutine calls get replaced with the call to &DB::sub(args)

I'm going to punt on this because I think I've already wasted more time than I'll ever recover :)
But thanks for your help!
