Subject: Add garbage collection at the end of each run.
X-Git-Tag: dm6-0.20100514~5^2~8
X-Git-Url: http://git.hungrycats.org/cgi-bin/gitweb.cgi?p=dupemerge;a=commitdiff_plain;h=79c8d21ca871e2f52d8de960cbf2534ba4509491

Add garbage collection at the end of each run.

You can trivially invoke the garbage collector by redirecting stdin
to /dev/null.
