This is a common problem with my wireless link as well.  Though I'm certain
it would be trivial to tell it to monitor itself in Python, I wrote a
little Bash wrapper around it.  I run Mutt on Win32 using Maildir on a
Cygwin managed-mount, so your mileage may vary as far as if the script
works out of the box.  Should work fine on any Linux box, but if you're
using Solaris or other operating systems with different options for "ps" or
"grep", it may fail.  Just change the options to match your system.

Just copy the text below to a directory in your $PATH as any name you like,
chmod 755 the file, and then run it.

===============================

#!/bin/bash
# A shell script to restart offlineimap if it dies.

OFFLINEIMAP=/usr/bin/offlineimap
LOGFILE=~/offlineimap.log
PIDFILE=~/offlineimap.pid

while [ 1 == 1 ]; do
    if [ "`ps ax | grep -f $PIDFILE`" != "" ]; then
         echo "offlineimap is still up @ `date`"
    else
        echo "offlineimap down @ `date`, starting it up."
        $OFFLINEIMAP >> $LOGFILE 2>&1 &
        echo "$!" > $PIDFILE
    fi
    sleep 60
done
