hypothesis still upset by deadline

Created by: wilsonmr

one of my jobs failed on Travis:

Unreliable test timings! On an initial run, this test took 1330.21ms, which exceeded the deadline of 1000.00ms, but on a subsequent run it took 859.85 ms, which did not. If you expect this sort of variability in your test timings, consider turning deadlines off for this test by setting deadline=None

perhaps my initial fix of

settings.register_profile("extratime", deadline=1000)
settings.load_profile("extratime")

should set deadline to None instead? I can't actually find the PR which added this so I can't remember why I didn't do this the first time
