This _should_ be handled OK by the kernel simply by not mounting the filesystem the second time. If you try and mount it a second time it _should_ just do a "bind" mount instead of a real mount, I think.
<stating the obvious> Rather than mounting the device to try and see if it is already mounted, use /proc/mounts or /etc/mtab or "df" or "mount" output instead. Doctor, it hurts when I do this... ;-). </stating the obvious>
Granted, this does appear to be a bug so the above will only work around it and not fix it. Al Viro is the one to pester about it. Hopefully he will see this email and reply (== fix the problem).

The 2.4.10 kernel is a bad one to use for several reasons, don't use it.
