> There is a race condition in SorlCore's constructor:
> - the metrics.indexSize call implicitly creates a data/index folder for that core
> - if the data/index folder exists, no segments file will be created
> - the searcher won't start up if there are no segments file in the data/index folder
> This is probably the root cause for SOLR-2130 and SOLR-2801 as well.
