Joining a busy forum overloads the device, which kills the Briar service

A user joined a forum with ~50 entries, looked at the forum (which was empty at the time) and then put Briar into the background. After a while the notification "49 new forum entries" appeared, but shortly thereafter the screen went dark and the device became completely unresponsive for around 10 seconds. After that the user was able to activate the screen again but the Briar notification was gone and seemingly the service had either crashed or was killed by the OS.
