    I probably agree with this, but I worry about the implications. The `deferredSupplier.get()` call might be very slow. Are we always doing this in a context where we accept that slowness (e.g. never called by `getNonBlocking()` without first checking that it's not a deferredSupplier).
    
    @alasdairhodge can you rebase this against master - we've fixed quite a few non-deterministic test failures, so hopefully the jenkins build will be better behaved this time.
