A test unit for thread cooperation with channels, simulates real case. Uses blocking channel operations.

Creates N=countProcessors() threads.
Launches 256 tasks and sends them via the first channel to worker threads
Collects results from worker threads in a separate consumer thread via the second channel
Checks if all tasks were completed
Tests both buffered and unbuffered channel implementations.
