Fixed fork() errors where forked thread is a copy of any cloned thread in parent address space.

Browse Source 
Upon fork, child was created in a new space but as a copy of any
cloned thread in the parent space. This was due to the search of forker thread
by its space id (which is shared among many cloned threads).

Now fixed.
