This breaks the site. Overloads the central DB. Reverted.
Detail: the s3 master (carrying centralauth DB) was stuffed with these reqs:
SELECT /* Database::safeQuery */ gu_id, lu_dbname, gu_salt,
gu_password,gu_auth_token,
[sorry, cut off as I didn't do a SHOW FULL PROCESSLIST]
We were getting reports of a lot of "too many connections" errors on
various wikis, mostly from people who *were* logged in but *not* with a
merged account. With a merged account, or anonymous, I didn't seem to be
having any problems.
It looks like something was triggering a lot of extra lookups, which
perhaps aren't getting properly cached.
