A folk remembered me that I modified this module for use in a plugin of mine. The difference is that since
socket_open does one operation in blocking mode it still can hang the server. So, this version brings
socket_open_non_blocking so all the operations can be done in non blocking mode. Source, win and linux version in the zip file here
