yes, getAspect() is actually a static member function of Thread that
returns the aspect of the currently running thread and since you call it
from the 'main' thread you get aspect 0. Try calling it from your
thread_func, it should return 1 there.

take a look at Doc/tutorial/progs/13multithreading2.cpp, it uses a
thread on aspect 1 to spin an object.
