Core/Source/GrowlApplication.m
2009-08-24 Every 30 seconds, post an Other event to trigger clearing of the autorelease pool; otherwise, we'll amass unreleased objects when the system is idle. This replaces a cycling NSAutoreleasePool system which solved the same problem but which posed problems in some future timelines.
2007-05-11 Added GrowlApplication, a subclass of NSApplication. This sets up and periodically breaks down an NSAutoreleasePool. This ensures that autoreleased objects are cleared from memory without waiting on the next time the user interacts with a UI portion of GrowlHelperApp.
