You get the idea.  This doesn't happen with other programs.  It seems to
be something specific to sbcl, though I could hardly believe that sbcl
is guilty of anything here.

Thanks!  It turns out I replaced FreeBSD with OpenBSD and I cannot
reproduce the problem on the OpenBSD system.  So, to me, personally, the
problem is eliminated---but there's something going on in FreeBSD, which
should be looked at.  I have no intuition on the problem.
