There's a question currently open, but with one vote to close as duplicate.

The <a href="https://superuser.com/questions/181510/how-to-enable-fast-user-switching-in-mac-os-x-10-6-4">open question</a> is about fast user switching in Mac OS 10.6.4 (aka Snow Leopard). 

The <a href="https://superuser.com/questions/76388/leopard-how-to-change-user-without-closing-applications-running">original question</a> has an answer that does correctly answer the new question, but has "leopard" in the title and is explicitly tagged as `osx-leopard`.

If we simply close the current question, future users might ignore the other because of its title and tag.

Options I see:

 - Leave the new one open as an answer for Snow Leopard
 - Close the new one and edit the original to either add the Snow Leopard tag or simply remove release specific wording and tags
