Comment 7 for bug 451741

Compiz is the only compositor I'm able to test. KWin and Xfce support DBus (as far as I know), so it might be possible to accommodate for them in the startup script. For others that don't support DBus like Metacity, xcompmgr, and Cairo (again, as far as I know) it might just be best to set the maximum wait time to 10 seconds. The worst case for any compositor would be the same as the current "sleep 10" which still isn't ideal.
