Control file sequential read

Listers,

On development I truncated a fairly large partitioned table, inserted the data from production via a db_link and then built partitioned indexes on the table. I was watching the v$session_waits for the session and noticed several sets of control file sequential reads during the index builds. I checked what file 2 was against the dba_data_files and it was showing rollback tablespace. Is this due to delayed block cleanout?
