Just a short bit. If "EXPLAIN SELECT" doesn't return, there seems to be
a very serious problem. Because I think EXPLAIN doesn't actually run the
query, just has the query planner run. And the query planner shouldn't
ever get heavily stuck.

I might be wrong, but there may be something much more substantially
wrong than slow i/o.
