The devel/p5-IO-Multiplex port
p5-IO-Multiplex-1.16 – handle multiple file handles
IO::Multiplex is designed to take the effort out of managing multiple file
handles. It is essentially a really fancy front end to the select system
call. In addition to maintaining the select loop, it buffers all input
and output to/from the file handles. It can also accept incoming
connections on one or more listen sockets.
