It does on master, i think, but unsupported doesn't run on PRs.

I'm happy to move it to supported if we're happy with it! I think since it runs all the main reactors plus asyncio, we can be relatively trusting of it being green now...


That build runs select, poll, epoll, and asyncio reactors.  So since there are about 12,000 tests, running 4 times, that is about 48,000 tests
for this builder.  That took 39 minutes.

Does it run under Coverage? attrs’ test suite took almost 20 minutes when running under PyPy3 and coverage so we switched it off for everything except py27 and py36.
