-- (default 8) milliseconds of CPU per execution; when the budget is spent the
-- remainder re-queues via C_Timer.After(0), so every continuation gets a
-- fresh watchdog budget. By construction no single execution here can
-- approach the watchdog limit, on any machine, at any step count.
--
-- NOTHING runs in the caller's execution: the first slice is deferred too,
-- so a caller that already spent real budget (a profile apply, an options

-- loading screens, so from a login-window caller the first slice lands on
-- the first frame after the screen drops.
--

-- handler and the chain CONTINUING: an async chain that died mid-way would
