A method in a computer system for enabling a process to manage the execution of a periodic, single-execution (PSE) task is disclosed. The process represents one of a plurality of processes executing on the computer system, and the PSE task represents a task to be performed once by one of the plurality of processes for each rotation of a periodic schedule. Each of the plurality of processes is capable of performing the PSE task and scheduled to perform the PSE task during the each rotation of the periodic schedule. The method ensures that the PSE task is performed only once by one of a plurality of processes during each rotation of the periodic schedule.
