The time it takes to mount depends on a lot of factors, but that's not
really the
problem. A solw mount will not affect udev, the problem is that udev
is not meant to
manage disks. E.g. who is making sure the disk is unmounted before it
is unplugged
(yanking it out whilst mounting/fsck'ing does not sound like a good idea btw)?

udisks is designed for this purpose, so I suggest using that. It uses
udev to get
events about plugged in devices (which is what udev is meant for) but does the
mounting/monitoring/unmounting itself.

I guess the udev page on our wiki should be "pruned" a bit so we don't give
people bad advice (on my TODO).
