Re: New index proccess in development version

When I was indexing I had similar upper memory usage between the different
versions -- just that the newer version got to the upper memory limit and
stayed there.  But maybe that depends on the type of documents that are
being indexed?  In other words, you think it's possible that Chris has
files that are making swish use more memory than in the previous version?

Is it really true that BSD doesn't free the memory?  I just assumed that
the reported number was not reduced after freeing memory.
