Topic: Memory Leak
I've confirmed a slow memory leak over time in Cog 0.07, over the space of a week constantly shuffle playing with 2000 songs in the playlist. When I restarted Cog, I got about 1.5G of free memory back as measured by MenuMeters.
I can do any detailed analysis you like, just let me know what you want to do. Other than that, this is mostly an FYI. Happy hacking!
