I'd say, that every granular synthesizer can stretch your sound to
infinity. Phase vocoding should be able to do this as well.  One of
the fun applications of grain synthesis is to "stop" right into a
sound, so that the movement slows down to a halt. 

Here is a quick'n'dirty example - without any finetuning of parameters
for cleaner sound - using the snycgrain~ external in Pd:

It's first playing some bars in original time, then slows to a stop,
then accelerates again up to doublespeed.
