Details
If the data queue is empty, the function waits up to the timeout value.
If data is not available in the data queue before the timeout expires, the return value is nil.
The entries in the data queue are removed in first-in, first-out (FIFO) order.
If the value is a table, a duplicate of the original table and any subtables is made. The duplicate table
does not contain any references to the original table or to any subtables.
