> CoW prepares local dir using "reindexCount" from definition builder. BUT, while re-indexing, at the time of construction of {{LuceneIndexEditorContext}}, the builder still has *non*-incremented reindexCount ({{IndexUpdate#collectIndexEditors}}) thereby updating the already existing directory.
> On windows, this often leads to deletion inside lucene to fail thereby failing re-index and leading to reindex loop -- this can be worked around by disabling CoW temporarily.
> That being said, this might be able to corrupt locally copied index.
