php-react-stream 1.1.0-1 (amd64 binary) in ubuntu groovy

 This library provides event-driven, readable and writable, streams
 for non-blocking I/O in ReactPHP.
 .
 In order to make the EventLoop easier to use, this component introduces the
 powerful concept of "streams". Streams allow you to efficiently process
 huge amounts of data (such as a multi Gigabyte file download) in small
 chunks without having to store everything in memory at once. They are very
 similar to the streams found in PHP itself, but have an interface more
 suited for async, non-blocking I/O.
