Hi Alex,

The information provided to Developer Tools is not currently exposed to
extensions, however my colleagues and I are working on an API to expose
similar data.  I think it would cover your use case.  You can read (or edit)
the proposal here:
http://code.google.com/p/chromium/wiki/ExtensionsPerfTraceAPI.

Currently this is only a proposal and is likely to stay experimental.  I'm
working on an implementation of this to do further experimentation - it
would be super useful if you wouldn't mind reading through the proposal and
providing feedback.
