I just started the testing and gnashing. The following is the test program.

use IO::Select;
use IO::Socket;
use strict;

my $lsn = new IO::Socket::INET(Listen => 1, LocalPort => 8080);
my $sel = new IO::Select( $lsn );
my $rc= $sel->select ($sel,undef,undef, 2.2);

#my $s= IO::Select->new();
#my $rc= $s->select (undef,undef,undef, 2.2);

print "\$rc=<$rc>\n";
print "\$! <$!>\n";
print "\$@ <$@>\n";

I have tried the above in different configurations of arguments to the ->select(...); and in no cases did the timeout fire. The program just blocked until it recieves a connection.

From another xterm I then did:

tuser> echo "x" |nc localhost 8080

which produced the following at the blocked test program:

$rc=<3>;
$! <Illegal seek>
$@ <>
tuser>
[download]

This may be moot if IO::Select doesn't process the timeout. The code examples in perldoc all show a fully blocked architecture using the 'can-read' sort of function.

Puzzling...
