src/pmc/tqueue.pmc - Threadsafe Queue

DESCRIPTION

Threadsafe queue class for inter thread communication. If you have an unthreaded program then please use an Array-like PMC.

     new P0, 'TQueue'
     push P0, some
     new P2, 'ParrotThread'
     ...

and in other thread (at least, when shared PMCs work :)

     shift P1, P0

Note: The TQueue must always be emptied before program exit.

void init(): Initializes the queue.
PMC *clone(): Returns the queue itself. No copy is made.
void mark(): Marks all the threads in the queue as live.
void destroy(): Destroys the queue.
INTVAL defined(): Returns whether there are any threads in the queue.
INTVAL get_integer()
INTVAL elements(): Returns the number of threads in the queue.
void push_pmc(PMC *item): Adds the thread *item to the end of the queue.
PMC *shift_pmc(): Removes the first thread from the start of the queue.
