I'm adding to this report that the Ubuntu php.ini file has instructions which are impossible to follow. The php.ini section on Debian session handling refers to ext/session/ (a different program is for Windows) which is not included in the Ubuntu PHP5 package. So Ubuntu does not provide PHP session cleaning.

; NOTE 1: PHP will not create this directory structure automatically.
; You can use the script in the ext/session dir for that purpose.

If we're going to use Debian PHP, we need to include the session directory creation tool. And the session directories need to be created, so the cron job will work.

Whether you interpret this as Ubuntu PHP not being functional due to uninitialized session directories, or as containing a bug which fills the disk with session files, or as having a cron job which cleans the wrong directory, there is something wrong with PHP sessions.
