File left locked after exception during init

[GoogleCodeExporter]

Hello,

You need to make sure that you close all locked files in RecordFile
as if the file is corrupted a Throwable is raised on init and a lock on teh 
file is kept from RecordFile - e.g. no way to delete the file pragmatically 
after this type of Exception ( Throwable )
