# Commit a9260cb

Skip fiber machinery for noop node callbacks

Fibers exist solely to let node callbacks ask about types; the noop
callback used by scope-effect-only walks does not need one, so do not
create or resume a worker fiber for it. Parked fibers are idle workers,
not pending work - skipping their no-op fuel starves nothing.
