WIP: subsystem runner test, still broken

Browse source 
using new thread synchronization

Disabled further tests, making one after another working.

Some notes:
 * currently running this leads to different outcomes on differnt runs,
   there are some races/unsyncronized things left, to be investigated.
 * I suggest to make Subsystems joinable, this prolly needs some work in
   the error handling department (thread-wrapper.hpp too)
 * using nonrecursive/waitable lock, recursive locks are have some bad
   taste unless absolutely necessary
 * after all a timed lock with polling is not the right approach to check
   for subsystem shutdowns, I opted against thread cancelation because of
   its programming overhead and complexity. We may refine this and allow
   synchronous cancellation (with an approbiate thread flag) in some cases.
