Quit that application fool!
It seems that Apple are taking notice of utilities like Eject Disks and building notice of what is preventing a disk being ejected into Snow Leopard (see
More Reliable Disk Eject at the bottom of the Snow Leopard refinements page).
As a result I will probably not be updating Eject Disks with feature updates once Snow Leopard is released, although bug fixes will still be released of course.
Update: I will most probably be investigating tying Eject Disks in with the system eject function using kicker.xml and configd, so development may continue of Leopard to try and make it similar to Snow Leopard.
