The Apollo Guidance Computer's software was designed to interrupt a lower-priority task in order to handle a more important one.
Notes on verification
Confirmed by multiple independent sources describing the AGC's priority-based executive/scheduling system, which shed lower-priority tasks (e.g., during the Apollo 11 1202/1201 alarms) to preserve critical navigation and control functions. Consistent with historical NASA documentation.
