I measured it using "time guile < /dev/null" and repeated it several
times.  Each time the execution time varies, thus I tried to make out a
general tendency.  And, sure, the benchmark suite would be a better test,
if it contained some relevant benchmarks.  This is, up to now, not the
case.

However, didn't you say that you had some nice benchmark application
called lilypond ;-)  If there was a significant change due to your gc
changes, I believe you would notice it, right?  However, performance
improvements are not the major objective of your current patches, at least
that's what I understand:  IMO the code cleanup is the important point
here.

Best regards,
Dirk
