Looks like I was right.

I had a query writing to a table.  I thought it would finish last night,
but it ran for > 24 hours.  I've killed it and changed the query so that it
will write to an output file instead.  I restarted the query, but now lag
seems to be recovering.  Lag is ~14 hours for enwiki and ~ 18 hours for
log.
