eio_busy — Artificially increase load. Could be useful in tests, benchmarking

eio_busy(
    int $delay,
    int $pri = EIO_PRI_DEFAULT,
    callable $callback = NULL,
    mixed $data = NULL
): resource

eio_busy() artificially increases load taking delay seconds to execute. May be used for debugging, or benchmarking.

delay: Delay in seconds
pri: 請求的優(yōu)先級：EIO_PRI_DEFAULT，EIO_PRI_MIN，EIO_PRI_MAX 或 null。如果是 null，pri 將設(shè)為 EIO_PRI_DEFAULT。
callback: This callback is called when all the group requests are done.
data: Arbitrary variable passed to callback.

eio_busy() returns request resource on success, 或者在失敗時返回 false.
