server: earlier disallow IO ops on unconnected bricks
...
Unconnected server bricks cannot work at the IO layer, but
are required for the strategy layer (in order to get strategic
information over the network even when IO is not yet possible).
Reflect this in the code, and report any potential communication
mischief as early as possible (safeguard).
Functional testing did not show a difference, but timing
behaviour should have improved.

server: improve CPU usage on slow throughput
...
Th problem is a distributed one, the scenario is very difficult to
reproduce, and would trigger massive occurence of false-positive test
results, and the classic yield() operation (as already implemented) is
not enough for a solution.
In a certain special case, give up the CPU via a linear backoff
algorithm. in order to prevent a plethora of followup effects, e.g. in
special situations like already happened OOM under a variety of hardware
and kernel configurations.
