More trouble?

Forgot to add (see below). Seems logfs_segment_read would be simpler
too if you fixed this.

[ Objects are the units that get compressed. Segments can contain both
compressed and uncompressed objects. ]

It is a trade-off. Each object has a 24 Byte header plus X Bytes of
data. Whether the data is compressed or not is indicated in the header.

Was my point really. Why do segments contain both compressed and
uncompressed objects?
