Hi,
Apologies for taking so long; generally this is a lot nicer.
I'll reply to each patch individually, but two more general questions:
a) Shouldn't compressBound be used somewhere to get the worst case
compressed size?
b) I think adding some trace points would be useful; it would make it easier
to
spot when you were waiting for threads etc.
