I've actualy seen this with a bunch of NFS clients idle, and sendmail stops delivering email until the load average drops. What's of more concern is the intense VM implementation Rik has done -- it's a great piece of work, but it appears when heavy swapping is going on, sendmail also stops delivering email as well.
