Writersdo not take reader_lock and can advance commit_page before publishing thecommitted length on the new page. rb_get_reader_page() can swap to thatpage, catch up with the writer and return NULL.\nHandle NULL through the existing no-data exit without warning. Remove thecaller's reader_page == commit_page check as well, since the reader-pagehelper already handles that case.
