OK, I can confirm the slow-down. The profile points to forward-line,
so I disabled cache-long-scans, and -- lo and behold -- the slowdown
went away. So this should be the workaround for the time being.
It looks like the overhead of caching newlines, which is supposed to
be small, is somehow very large in this case.
