Hi I just wanted to send a ping from my side. On this suggestion for quickfixing compression bug.

[1313e]

This one will have to wait until #138 has been dealt with.

[hernot]

I would have decided otherwise, as this pr is a suggestion how to quick fix #140 for current production 4.0.0 release. Which i would consider more important than the next step towards unleashing the true powers of hickle proposed in #138. And #138 renders this pr anyway obsolete as it allows to handle, and does so, compression issue #140 on a lot more fine grained and granular level than would be consistently be feasible in 4.0.0 release. Reviewing and if positive merging this first would provide imho a lot more time for thoroughly discussing and reviewing #138 which is admittedly a big step.

This one is obsolete, as this fix is already implemented in 4.0.4.
