I'll clarify what I meant.
Normally, user will see only one sheet at a time. There won't be any sort of step-by-step sheet switching within a single task (like in Xcode 4 when creating a new file). The only issue I'm trying to solve is presenting a username/password dialog when it was invoked by a background task (not a direct user action). And since I may have several such background tasks running, I can potentially present several dialogs at once.
Again, normally you'll see no dialogs at all (when the password is already stored in keychain) or a single dialog when a new repository is added or the password was changed. But I should have a nice fallback for a case when several dialogs get popped out. With floating modal windows it is not a problem: they live independently from each other. But floating modal windows look awful, so I want to use sheets. And to present them correctly, I need to maintain some sort of a queue for these sheets.

In the very rare scenarios where multiple sheets are used to accomplish something, I've never seen them presented as anything other than a strict sequence. When sheet N is dismissed, if more information is needed sheet N+1 will be presented. When sheet N+1 is dismissed, the user is shown the unobstructed window. When you say "stack" I infer that you intended to re-show sheet N.
