Thomas Schoebel-Theuer ad3f5fa943 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.
