basically 'cause there is no reliable way to correctly "abort" a 
thread. nobody knows what is really going on inside it, so 
shooting it down is very unsafe. i.e. aborting thread in the 
middle of something is very-very wrong, so it is programmer's 
responsibility to stop (or detach) all the created threads.

note that fibers *will* be collected.
