|
Starts a repeating background worker process.
|
|
|
|
`exec_func` runs in a loop, and the worker sleeps for `interval` seconds between executions.
|
|
|
|
If a process with the same `key` is already running, `task_repeat()` does not start a second worker and instead returns the PID of the existing one.
