RT only builds the squished css/js once per child process.  If you're
actually seeing it built on each request, something is horribly wrong
and isn't something we've seen or been able to replicate.

Also, if jsmin is breaking the UI, that's the first report I've seen
of it.  Can you file a bug report with more details?
