When libsbuf was ported to userland, sbuf_printf() was pessimized due to
the limitations of libc's printf().  This makes certain parts of
pseudofs extremely inefficient: for instance, if you read from a
/proc/whatever that's backed by an sbuf, it has to generate the entire
file even if you only asked for a small chunk at a large offset.
