Way back when I was taking photo classes at the community college we used
something called "Hypo-Clear" which dramatically reduced the amount of time
required for rinsing... As I can remember, it was a bath after the stop,
soak a print for a couple minutes, then all you needed was a 5-10 minute
wash... and this was Afga Brovira (real paper, not RC). I don't know if you
can also use this stuff when washing your negatives, but I don't see why
not, unless someone can correct me.
