the tied %udat does a shallow check to see if anything
needs to be stored.  i think most of us who use it do something
like this in code that changes %udat:
$udat:{TIME}=time;

this guarantees that the shallow check will be successful and
that the tied %udat is stored in the session.

you can invoke a session write directly if you prefer, see the
documenation.
