Unfortunately there isn't really any way to implement something like
that, as it is hard to detect if a web user has 'left' a page and gone
to some totally different website, or is just sitting there looking at
it. Maybe you could write some code that uses the $session_id variable
to update a file of locks and uses timeouts to prevent locks from being
held too long ... but there is no support or standard functions for this
kind of locking built into webmin.
I did consider it at one point, but gave up because it was too hard!
