We will probably rewrite this as part of the console output rewrite.

This won't work the same as it used to - 'i' needs to be passed into ContentTask for the string to be able to access it as an argument.  See https://wiki.mozilla.org/Electrolysis/e10s_test_tips#ContentTask

Not sure if I did this correctly, so please let me know if I need to change something.

Comment 9

Forgot to mark the other patch as obsolete. Is there a way to do this after the fact?

Yeah, looks right to me.  You could also check this in the test by 'pausing' the task with `yield new Promise(r=>r)` and then opening up the page's web console to make sure it's logging correctly.  Try push: https://treeherder.mozilla.org/#/jobs?repo=try&revision=97e42d2d640b
