[ECOS] R: [ECOS] Thread execution time

["Michele Portolan" <michele dot Portolan at imag dot fr>]

What do you mean by "ticks"? Do yo mean clock cycles?
I am working on possible modifications of context-switching mechanism to
implement fault tolerance funtionalities.
I have just begun, there is not much yet, but I need these data as a
comparison and make some "a priori" evaluation
