Bug 1309865: Don't expect that an event will be fired within a given time. r?gerald We only care that we will enter suspended mode after a minimal time. On slow machines (like the linux try box) there are so many things at play that could delay a particular event. So we remove the upper time test. MozReview-Commit-ID: IAZVyuetYVp
