Right.  The only reasons why the current tmpmfs_flags doesn't
include the `-o async' option too are:

    a) It didn't back when it was all hardcoded in the script

    b) I didn't think about adding it by default when revision
       1.230 of src/etc/defaults/rc.conf was committed by me

If it does improve things, we should probably make the change :)
