That problem afflicts KinoSearch 0.1x, but not KinoSearch 0.3x or Lucy.

There is a single write lock, which is held from Indexer->new through
Indexer->commit.  Multiple processes attempting to write to the same index

There are multiple strategies for managing this limitation, such as queuing
or utilizing Lucy::Index::BackgroundMerger, but the limitation remains.
