Judging by the filename (and a quick trip to google code search) it's a test file from Net::Daemon which uses IO::Socket so I'd bet it's just read from the second anonymous glob generated for a socket (the first would have been named GEN0). You can get the same handle names yourself with gensym from the core Symbol module.
