Yes, yes, I have.  Perhaps my bar for "it sucks" is higher than yours.

I wrote a dd-alike that was specifically designed to overlap reading
and writing (one process for each, with data passed beween them through
shared memory), so I know a little about that.  Such things can give
you at most a factor of two speedup, usually less because the producer
and consumer are running at widely disparate data rates.  (Unless you
have unusually slow disk or unusually fast network.)
