So we now have 2 implementations candidates. :-(

Leo had a similar problem.  I don't have time to dig into it right now,
but I suspect that this part of the behavior can be dropped.  If not,
maybe something like (sit-for 0) will do the trick.

can't use CL macros (because CL macros use functions defined in
