I'm trying to write a server for doing some things remotely on another computer. I start the server, and it waits for me to connect, then use a continuous loop for the duration until a condition breaks it. 
my $server = IO::Socket::INET->new(LocalPort => 666, 
    Type=> SOCK_STREAM, 
    Listen => 0, 
    Proto => "tcp");
die "Can't open socket" if (!$server);

[...the main loop...]

close($server);
log_msg("Connection lost.\n");

I added the close() because when the program ends by itself this way (as opposed to being terminated with ^C), the port is evidently left blocked -- when I try to restart

Can't open socket

Which I take that to mean the port is not available. This lasts about a minute then the port is free again. Why would it be freed by ^C but not by close()?

The OS is linux.
