I am checking Day objects in my schedule Dictionary and want to know what to do about the Day pointer when I'm done. Build and Analyze doesn't complain about it, but it just sits there taunting me. I feel like it's just sitting there when the function finishes and maybe even a new one gets created each time through the loop. Also, when r...
I've stumbled upon a problem in the application I'm developing using cocoa. I need to do some processing, and I'm doing it on a separate thread.

Excluding Cocoa (and its NSThread), what multithreading libraries would you recommend? The application's engine must run on multiple platforms (Windows, Linux, MacOS, iPhone), and be multithreaded. Abstracting the library to compile against platform-specific MT libraries is possible, but incurs an extra layer of overhead and complexity...
