pub const MAX_DRAIN_LINGER_MICROS: u64 = 100_000;Expand description
Ceiling on RuntimeOptions::drain_linger in MICROSECONDS (100ms).
Validation (and, defensively, executor construction) clamps the budget
here: lingering exists to bridge micro-scale gaps between scheduling
waves, and a lingering drainer holds a pool worker plus an
active_drainers slot while idle, so budgets beyond this bound stop
tuning the wave optimization and start pinning workers.
