A while back I posted complaining that importing quixote breaks when
the quixote package is not at the top level.  I suggested using
relative package imports, but it turns out that wasn't the real
problem.  The real problem is that publish depends on util (for
dump_request), and util depends on publish (for a lot of things).  Is
util a client of quixote or the other way around?

publish uses util for dump_request
session uses util for randbytes

I suggest that either these two functions go into a lower-level
_quixote_util (or something) module, or move into publish and session,
respectively.  A lower level util module may be preferable because
then the high-level util can import it also and not break client code
that uses dump_request.


Any better ideas?
