    It would be good to document what this function assumes about channel locks.  i.e., which channel locks does it assume are held or not held when entering this function?



trunk/main/features.c

    I'm not sure why this is required.  Why not just block on lock() and then check to see if the channel is a zombie / has been hung up when you get it?
