drain_timeout_has_headroom
Function
This function is defined in the protocols module.Return whether the supervisor stop-timeout leaves room to drain. Pure predicate used by a startup sanity check. A supervisor whose stop-timeout is shorter than
drain_timeout + headroom will SIGKILL
the gateway mid-drain, leaving no explanation. This returns False only
when we can prove the headroom is insufficient; when either value is
unknown (None) or non-positive it returns True (fail-open: do not
emit a spurious warning when we cannot tell).
