As concluded in following thread[1] and mentioned by mount(8), mounting 
filesystems with 'async' flags can lead to corruption and should be avoided if 
data loss isn't calculated risk. But official documentation[2] about power 
management contains following statements:

You can place commands inside of these scripts to change the power management 
settings when using battery or line power. Here are some example scripts:



mount -u -o async,noatime,nodevmtime /
mount -u -o async,noatime /usr
atactl wd0 setidle 5


BTW: mentioned on WWW /usr/share/examples/apm sample script, at least
on -current, doesn't contains 'async' flag in remount command for 'battery'

Remove 'async' flag from examples on
