(ad infinitum, until "Output exceeded 52428800 bytes, remaining output has been truncated")
It's actually only one tab that browser-test.js fails to remove, so it loops infinitely.

Given the fragile state of tinderbox right now, I would very strongly recommend disabling this test until it can fail in a reasonable way, without the thousands of TEST-UNEXPECTED-FAILs.

It's not necessary. It just makes this code use the "official" API.

We can close this bug. Not going to try to resurrect the parts of this test that have been disabled years ago.
