- * How it works:
- * A pthread_t is a struct (2x32 bit scalar types on IA-32, 2x64 bit on IA-64)
- * which is normally passed/returned by value to/from pthreads routines.
- * Applications are therefore storing a copy of the struct as it is at that
- * time.
- *
- * The original pthread_t struct plus all copies of it contain the address of
- * the thread state struct ptw32_thread_t_ (p), plus a reuse counter (x). Each
- * ptw32_thread_t contains the original copy of it's pthread_t.
- * Once malloced, a ptw32_thread_t_ struct is not freed until the process exits.
- * 
- * The thread reuse stack is a simple LILO stack managed through a singly
- * linked list element in the ptw32_thread_t.
- *
- * Each time a thread is destroyed, the ptw32_thread_t address is pushed onto the
- * reuse stack after it's ptHandle's reuse counter has been incremented.
- * 
- * The following can now be said from this:
- * - two pthread_t's are identical if their ptw32_thread_t reference pointers
- * are equal and their reuse counters are equal. That is,
- *
- *   equal = (a.p == b.p && a.x == b.x)
- *
- * - a pthread_t copy refers to a destroyed thread if the reuse counter in
- * the copy is not equal to the reuse counter in the original.
- *
- *   threadDestroyed = (copy.x != ((ptw32_thread_t *)copy.p)->ptHandle.x)
- *
