right, if that happens.   you might also get a fifo if already been
used interpreters are in use.  the interpreter pool behavior is also
subject to change in such a way that would make trying to use 'lifo' or
'fifo' even more wrong/confusing.  so let's call the interpreter 'nifo'
neither fifo nor lifo.
