Re: NSTimer preventing sleep?

Hi Jacob-

Consider watching for a sleep notification from the system and pausing 
whatever it is you are doing until you get a wake notification. 
Research NSWorkspaceWillSleepNotification for more info.  Here's some 
relevant code:

// register for sleep notifications
[[[NSWorkspace sharedWorkspace] notificationCenter] addObserver:self 
selector:@selector(willSleep:) name:NSWorkspaceWillSleepNotification 
object:[NSWorkspace sharedWorkspace]];
[[[NSWorkspace sharedWorkspace] notificationCenter] addObserver:self 
selector:@selector(didWakeFromSleep:) 
name:NSWorkspaceDidWakeNotification object:[NSWorkspace 
sharedWorkspace]];

Hope this helps!

John
