Yes, more or less. You indeed have 1Mb increase in memory usage
for every four or five iterations. Now the magic scheme command is '(gc)'
and you will have to redo your thirty iterations before noticing
further increase. So maybe it is just the gc which is not well synchronized.
You may try to see whether doing a '(gc)' also solves the problem with
the increase in memory usage during idle time.
