lock on the session.

As you put data into the session hash, Session squirrels it away for
later use.  When you untie() the session hash, or it passes out of
scope, Session checks to see if anything has changed. If so, Session 
gains an exclusive lock and writes the session to the data store.  
It then releases any locks it has acquired.  

Note that Apache::Session does only a shallow check to see if anything has
changed.  If nothing changes in the top level tied hash, the data will not be
updated in the backing store.  You are encouraged to timestamp the session hash
so that it is sure to be updated.

When you call the delete() method on the session object, the
object is immediately removed from the object store, if possible.

When Session encounters an error, it calls die().  You will probably 
want to wrap your session logic in an eval block to trap these errors.
