blockdev mount detection

[William Jon McCann]

Hi,

I've been trying to debug why gnome-vfs/nautilus is not detecting CD/DVD 
mounts correctly for me when using gnome-volume-manager to automount 
discs.  It seems like there is a race between the sysfs mount detection 
and when it is available to getmntent_r via /proc/mounts.  So the effect 
is that blockdev.c:update_mount_point() doesn't find the mount entry and 
doesn't update the "volume.mount_point" property.  I have appended the 
debug output (I've added another HAL_INFO inside the while loop of 
update_mount_point).

To test this, I added a sleep to the beginning of update_mount_point and 
it was then able to find the mount entry.

What do you think?

Thanks,
Jon
