That's the bug. Nobody SHOULD use readNewest, which has been
introduced (by me ...) as a quickfix on top of issues we had.

Connection policy is a system design concern. If one wants to build a
system where the controller should process 10 samples queued in a
buffer, then so be it. Except that readNewest was really made
necessary by the bug Johannes describes.
