Only if you redefine the meaning of bgwriter_percent. At present it's
defined by reference to the total number of dirty pages, and that can't
be known without collecting them all.
If it were, say, a percentage of the total length of the T1/T2 lists,
then we'd have some chance of stopping the scan early.
