From what I've read, Gingerbread has some SOD problems which have been reported, for example,
here and
here. Have you ever experienced it?
This rom is rock stable. I haven't had any issues except the known ones (e.g. bluetooth 60ma standby drain). I don't know if the rom itself can be improved any further as the concept of this rom is clean and minimal (most flexible), which is just what I needed. If it could be improved then it's the kernel that you can change. I'm using HyperKernel v5 which is great, smooth, battery saving (UV) and supports extended battery as well
