you can't count on the cache being hot at all. i spend most of my time
working on a compute server with several other coworkers, the kernel
cache is shared amongst lots of apps, not just svn. i very rarely get
lucky with hot cache svn status. this is the norm for all the
companies i consult with in the silicon valley area.

so greg, will i be able to start testing any of this when the 1.6
branch comes along? will most of your changes be in there by then?

thx!
