Files and GC

With rv-file.ss there is now a nice collection of file interfaces that
make it possible to integrate functional reactive scheme code into a
stateful unix world.

     rv.ss       reactive values & computations
     rv-file.ss  monitored files as RVs
     mfile.ss    managed tempfiles as scheme values

These should now completely replace the dynamic.ss abstraction.  Let's
start changing sweb.

Best approach seems to be to do this in parallel.
