Figured this one out. A connectivity change intent was causing other apps and system services (notably maps) to increase system load dramatically. One of my own responses to a connectivity change was to cancel/set several alarms.
Seems that when a device is under high load, alarm manager set/cancel calls can take around half a second so the chances were that when the ANR occurred it would be there i.e. the ANRs weren't caused by AlarmManager code hanging but by it taking so long.
