    $capacity is count of stack in buffer.

    for example :

    <?php
    use parallel\{Channel,Runtime};

    $test = function($ch){
    var_dump($ch->Recv());
    var_dump($ch->Recv());
    var_dump($ch->Recv());
    echo     'Sleep'.PHP_EOL;
    sleep(3);
    echo     'Call Recv()'.PHP_EOL;
    var_dump($ch->Recv());
    };

    $t1 = new Runtime();
    $ch = new Channel(3); //buffered channel
    $ch->Send('abc1');
    $ch->Send('abc2');
    $ch->Send('abc3');
    $t1->Run($test,[$ch]);
    sleep(1);
    echo     'Wait for Recv()...'.PHP_EOL;
    $ch->Send('abc4'); #php waits for only one stack of channel to be empty(by Recv() method)
    ?>

    result:
    string(4) "abc1"
    string(4) "abc2"
    string(4) "abc3"
    Sleep
    Wait for Recv()...
    Call Recv()
    string(4) "abc4"

    Please note $capacity unit is 1 MiB each, not bytes
