parallel\Events::setTimeout — Behaviour

### Description

By default when events are polled for, blocking will occur (at the PHP level) until the first event can be returned: Setting the timeout causes an exception to be thrown when the timeout is reached.

This differs from setting blocking mode to false with parallel\Events::setBlocking(), which will not cause an exception to be thrown.

public parallel\Events::setTimeout ( int `$timeout` ) : void

Shall set the timeout in microseconds

### Exceptions

Warning

Shall throw parallel\Events\Error if loop is non-blocking.
