One file per thread might work, though I suppose it would break down
if you had many thousands of threads...

Of course, if you were running behind lighttpd or similar, you could
have it doing request logging.

As I (unfortunately :) ) don't see anything like 400 requests per
second to my personal projects, this isn't something I'd really be
interested in looking into too much myself.
