If some objects were on the stack of the thread proc, their 
destructors run, yes, as usual for leaving a scope. Strings don't 
have destructors, afaik.
Thread-local storage gets cleaned up too. But everything that 
lives in heap, stays there, until GC finds them. Objects in heap 
don't have any information on them  which thread they belong to.
