your post give me one idea: what about using am Rodeh Btree[1], to create concurrent snapshots of the running kernel, in this btree, so we could switch them in runtime.. you compile a new version (CRC does not match) them it will create a new branch/snapshot on memory and will start from there.. kernels of course should be designed in a transactional way manage states, etc.. rsrs.. anyway just a wild idea, dont know if its even useful doe..
