Occasionally a job may be run when the app is in a network-restricted mode, like a form of doze. When this happens, jobs can timeout due to lack of network access, causing a cascade of job delays. This is particularly bad in the case of message retrieval. To prevent this, if a job that normally requires network detects that no network is available when running, then we start a foreground notification.
