pKillVar is defined as a global elsewhere in the script.
Its value is "pendingScope".


global $pKillVar;
$delete_me = $pKillVar;
global $$delete_me;
unset($$delete_me);

does NOT work. however:

$delete_me = "somevar";
global $$delete_me;
unset($$delete_me);

does. Seems to be a problem unsetting variables in the global scope. Have been having numerous problems related to such.
