IMO, not reparsing is a performance optimization that should not be surfaced.  I think the Inspector should show the same parse errors, whether or not the resource was cached- this is what happens for other cached resources that have syntax errors, like JS.

The inspector does not currently show whether the stylesheet was reparsed or not. (In fact, it gets reparsed by the inspector many times, but this is transparent.) Joe and I had to dig into WebCore and use breakpoints to get some ground truth on whether something was reparsed.
