the problem is not unfamiliar to the synchronisation issues in
you're basically calling for making the action and setting of the
property an atomar operation. this is hard enough for simple operations
like incrementing a variable, making something complex like changing a
window's properties a window and then setting an atom on the X server
indivisible doesn't make it easier.
so no - I don't think there's a way to get around it.
