Status: UNCONFIRMED

Steps to reproduce:

The IMVU client has xulrunner embedded in it, and a flash widget embedded inside of that.
The flash widget makes network requests, the result of which get cached to disk.


Actual results:

Generating temporary files performs a linear search for available filenames, which can create significant UI lag when there are enough files.


Expected results:

Temporary files should have more-unique filenames at initial generation, so that a search does not take very long to find an available filename.

There is a patch attached that should fix it.
