Check for stack overrun in standard_ProcessUtility().
ProcessUtility can recurse, and indeed can be driven to infinite
recursion, so it ought to have a check_stack_depth() call. This
covers the reported bug (portal trying to execute itself) and a bunch
of other cases that could perhaps arise somewhere.
Per bug #15428 from Malthe Borch. Back-patch to all supported branches.
