Sounds like a good time to bring the lsprof branch up to date!

I've now done so and its new home is here:
	http://www.lag.net/~robey/code/bzr.dev.lsprof/

Using that branch, I did a sample "bzr branch" of bzr.dev from my  
local repository to a non-repo folder (forcing it to copy revisions),  
and posted the results here, for the curious:
	http://www.lag.net/~robey/code/local-branch.html

The script I used to generate HTML from the lsprof output is here:

I'm curious why you thought that, by the way...
