/**
 * This is the experimental package of mux.lease.  Right now, this is all
 * experimental code around leasing, especially leasing around garbage
 * collections.  We haven't hammered out exactly what the api will be, so it's
 * in large part private and is subject to change.

 * NB: large parts of this package might suddenly end up in util-jvm
