The doc comment named RUSTFS_LOCK_ACQUIRE_TIMEOUT with a 30-second
default, but the function reads RUSTFS_OBJECT_LOCK_ACQUIRE_TIMEOUT
with a 5-second default. RUSTFS_LOCK_ACQUIRE_TIMEOUT is a real,
separate knob read by the lock and scanner crates, so tuning the
documented name silently has no effect on this path.
