@dhermes, @daspecster I'm tempted to kill off the Travis for the PR and merge immediately: the system tests pass with this change on my box, and tox -e lint is happy. Since the only point of it is to try to fix post-PR builds, I'd like to know whether it works. :)

The resource ID has per-second granularity on Travis. You probably want to go lower by a factor of 100. Add an optional argument to multiply seconds in time.time() before casting to an int?

@tseaver I urge you to resist the temptation. Travis won't run your job for hours so it's not worth subverting the review process

I just read the definition of "subvert". A very dramatic word

We're already mangling in the TRAVIS_BUILD_ID into the unique_resource_id return value on Travis: are you worried we will be running two jobs with the same ID? The theory here is that reusing a topic ID within one run is the source of the flakiness we are seeing in #2163 and #2192.

That means it will be double that number of hours before we know whether it works.

Sorry I didn't realize your prefixes were unique, so it's moot.

LGTM to merge (no need to wait on Travis if you've run all the tox environmentsvthst Travis will)

*environments that (typing on phone, sorry)

Fingers crossed

W00t! the remaining failures are due to #2176.
