session_set_save_handler(.... list of handlers ...);
session_name('whatever');
session_start();
$tmpvar='asdf';
session_register('tmpvar');

When I actually run the above code, the open handler is run.
 The read handler is run, but then the write handler is not
executed.  Shouldn't it be executed when session_register()
is read?

Have you set session.save_handler in php.ini to user?

Yes the session module is set to "user" (this is done
automatically by session_set_save_handler() I believe).
Initially executing the script the handler was set to files,
but then I let the set_save_handler change it over to the
'user' module.  I have also tried to forcefully set the
handler to user, but still the "write" handler never seems
to be executed.

Please read this manual page carefully:

php.ini does not require session.save_handler to be set to
'user' in order to manage user sessions.

session_set_save_handler() appears to auto-change the
handler to 'user' when called.

the resolution to my problem is that the "write" call
actually occurs AFTER the output is sent to the webserver.
So my debug output was now displaying when echo'd... i had
to save to a file instead.

This may be something that needs to get added to the
official documenation... that the "write" handler doesnt
occur real-time, but at the end of handling the script.
