Ok; I started looking at the code, to see if I can help with this...
And you are right: it is not easy to fully understand snow.c code ;-)

Yes... I was quite surprised by slice_buffer_load_line() and 
slice_buffer_release()... I was thinking about submitting a patch for
these 2 functions, but I see you want them to be removed

I'll try to see if I can understand enough of the code to revert that
change. Just to be sure: r4101 was an optimisation, right? So, if I 
properly remove it the output of the encoder/decode should not change, 
right? (Is "make test" enough for checking if my modification is ok?).
