Increase the granularity of calls to start_writeout() when
early_writeout is used. This results in a smooth progress display during
writeout, rather than a noticeable pause each 20% of the way through.
I think performance shouldn't be hurt, since we're still batching pages
1% at a time, down from 20%. A normal image has 10's of thousands of
pages (mine 512M laptop is ~55000 pages, for example) so 1% is still
~500 pages or ~2M at a time.
