[ http://issues.apache.org/jira/browse/LUCENE-753?page=comments#action_12459805 ] Yonik Seeley commented on LUCENE-753: -------------------------------------
CSIndexInput synchronization could also be elimitated if there was a pread added to IndexInput public abstract void readBytes(byte[] b, int offset, int len, long fileposition) Unfortunately, that would break any custom Directory based implementations out there, and we can't provide a suitable default with seek & read because we don't know what object to synchronize on.
