Hi Alexander,

Are you still interested in reviewing those patches? I'll take a look at
0001-0003 to check that your previous feedback was addressed. Do you
have any comments about 0004 / 0005, which I think are the more
interesting parts of this series?


Attached is a rebased version - I realized I forgot to include 0005 in
the last update, for some reason.


regards
