I'm glad to read from the ticket there is an OFF switch to this.
I must say I delete with frequent regularity files 7-15+GB on
XFS and it never takes more than a couple seconds and
I've never seen it interfere with recording threads.  Something
as slow as described above, 16 hours to delete 500MB...  Not
very useful when my system can write 30GB or more per hour of new
recordings (3 HD tuners and 3 SD tuners if they are all running).
