we just talked this over on irc and came to the conclusion that it'd be 
good to add:
 pose = action.getPose(framenum)

Joseph is on that, and i suspect with that added and the already 
existing bone.insertKey that he informed me about, the pose key insert 
methods i had in object.c are probably not needed anymore.

glad that some clarity came to this,
