Except with 10 concurrent clients accessing the box, it does give a bit
larger improvements:

imaptest clients=10 secs=30 seed=1
    Logi Sele Fetc Fet2 Stor Dele Expu Appe Disc 
    1273 1272 1262 1262  633  493  493 1406 1263 
m   1316 1315 1305 1305  659  509  508 1392 1305 
f   1312 1311 1306 1304  650  494  493 1467 1301 
f+m 1644 1641 1634 1633  769  728  727 1810 1634 

Without fsync_disable=yes the values between mmap_disable=yes/no were
pretty much the same, sometimes one was faster than the other.
