Hmmm, the Solr wiki (seems to) states: "For example, if you set
mergeFactor to 10...there will be no more than 9 segments in each index
size."

Using a nightly build from 2 nights ago, which has lucene r768336 in it.
Since then the number of segments are increasing with every index, and it's
looking like
mergeFactor is no longer being honored.
Is this a testcase (using the solrconfig.xml from the test directory)?
If so, I recently changed the settings to create more segments - too
many cases were resulting in a single segment, which isn't as good for
test coverage.
e.g. have a mergeFactor of 10, but 18 segments in the index.
mergeFactor 10 means a maximum of 10 segments at each "level".
if maxBufferedDocs=10 with a log doc merge policy (equivalent to
Lucene in the old days), then you could have up to ~ 10*log10(nDocs)
segments in the index (i.e. up to 60 segments for a 1M doc index).
