And since it looks like it doesn't matter all that much with non-XFS, I
don't think I'll bother.

My 30 second benchmark runs showed this today:

m: mmap_disable=yes
f: fsync_disable=yes

imaptest clients=1 secs=30
       Logi Sele Fetc Fet2 Stor Dele Expu Appe Disc 
m    : 1502 1502 1501 1501  762  405  405  511 1501 
     : 1495 1495 1494 1494  780  407  407  513 1494 
f+m  : 1572 1572 1571 1571  802  439  439  534 1571 
f    : 1540 1540 1539 1539  770  416  416  517 1539 

So fsync_disable=yes does help a bit, but not nearly as much as in the
XFS benchmark where none -> f+m change gave 2-4x higher performance.
