Module: HotCell::Supervisor::Timed

Included in:
Child, Sweep
Defined in:
lib/hot_cell/supervisor.rb

Overview

The one deadline the supervisor enforces, on a worker and on the sweeper alike: from started_at, for deadline seconds, killed once. killed_for is the one-kill latch — a killed process stays here until the reap, and without the latch it would be re-killed and re-logged on every pass until then. See Child#overdue? for the measurement behind that.
