for what it's worth...
in php 4.1, using unset to destroy a session variable, i.e. unset($_SESSION['variable']);
destroys it by erasing variable information but leaves behind the variable name appended with a
'!' in front of the name in the session file... leaving the session file larger and x
bytes wasted depending on the variable name length
