[ic] usertrack and tmp dir

[Barney Treadway]

After combing through the archives and searching the site I can find nothing
regarding what to do with this 28MB usertrack file. Can i clean it up? Can i
delete it? Can I compress it?

On secondary note, I also have a few thousand directories sitting in
/catalogs/mystore/tmp and no one seems to care about them. I know about
ScratchDir etc but can I kill these subdirs when I run expireall?
