PR 5990
* descriptors.h (Open_descriptor): Add is_on_stack field.
* descriptors.cc (Descriptors::open): If the descriptor is on the
top of the stack, remove it. Initialize is_on_stack field.
(Descriptors::release): Only add pod to stack if it is not on the
stack already.
(Descriptors::close_some_descriptor): Clear stack_next and
is_on_stack fields.
