Meanwhile the choice between SortedVIntList and OpenBitSet has been removed from the trunk (development version), that now uses OpenBitSet only: https://issues.apache.org/jira/browse/LUCENE-1296
In case there is preference to have SortedVIntList used in the next lucene version (i.e. in cases when it is smaller than OpenBitSet), please comment at LUCENE-1296.
