Hi Gleb!
This commit has broken mips32 on my 128MB RAM routerstation pro board.
I've tested the commit before this one (and it works).
I've also tested today's -HEAD as there was some subsequent fixes to
the sfbuf code. It hasn't completely fixed things - I still see
processes throwing VM errors:

.. so how can we debug what's going on?
