Modal session when opening a sheet

Subject: Modal session when opening a sheet

My application has to do some background work while a sheet is open.
Using NSThreads in this case should be avoided for a number of reasons.

I would like to use a modal session, with my process loop calling periodically [NSApp runModalSession:(NSModalSession)session]

The problem is how to get the NSModalSession value for the sheet session. While the standard beginModalSessionForWindow: returns an NSModalSession value, the beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo: method i need to use returns void. (suggestion: wouldn't it make sense if it returned the NSModalSession?)

Any idea on how to recover the NSModalSession value for the current sheet? (Or maybe i simply overlooked something?)

Andrea
