I disagree.  I added a test inspector/timeline/exception-in-injected-script-while-recording.html which is based on inspector/timeline/debugger-paused-while-recording.html.  Note that the original test was previously excluded, and I fixed a bug for it and unskipped the test (see http://trac.webkit.org/changeset/180901).

I was warned that the test was seen to be flaky before, but I since I fixed one issue for it, and I wasn't able to reproduce the flakiness locally, I unskipped the test.

The proper remedy is to restore the skipping inspector/timeline again.  I will do this while I take a second look at why the tests can flake now that I have examples of their flakiness to study.
