Ah, switching our session table to InnoDB solved this problem for us. 
You guys probably have more sessions in your table than us though.

In fact, we have switched almost all our of tables to InnoDB.  The only 
ones left either are for logging, need to use some feature of MyISAM or 
are unimportant.
