For a simple application as a multithreaded ray-trace the current
implementation seems to work but if a thread creates threads it'll probably
crash again. To make this work the prototype of parallel_mapping() has
probable go to parallel.h (where parallel_cpp11thread() should go to) and
be used in parallel_cpp11thread(). And, the semaphores probably need a fix
too, as already mentioned.
If a GCi student reads this and wants to work on this: Take the "Test and
report on new C++11 parallel threading implementation" task, make sure you
are using C++11 threads, test them (make the program crash ;), or write a
test program (this could be easier to do and to reproduce), and submit your
findings. Based on this we can create a new task for fixing the bugs.
