<p dir="auto" style="color: #3a383f; margin: 0px 0px 1rem;" align="initial">The output thread of a regulator creates the rate monotonic period which
it uses. It deletes that period at the label <code style="font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; margin-top: 0px; font-weight: inherit; overflow-wrap: break-word; white-space: break-spaces; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; word-break: keep-all; padding: 0.125rem 0.25rem;">exit_delivery_thread</code>, and
that label is the only path to the delete.</p>

The helper
deletes the output thread where the caller gives it zero ticks. A thread
which the helper deletes never reaches the label. The period object then
stays allocated for the life of the system, so the application loses one
period of its configuration for every regulator which a caller deletes
this way.</p>

of the create loses one.</p>

It deletes the period in
the helper. Found in the review of that merge request. This description
was created with Claude Code assistance.</p>
