Hi, I don't have any trouble with Glib. Here are few examples. If need be put your stdin reader in a thread. These work well on Linux, I hope they help you sort it out.

#!/usr/bin/perl 
use warnings;
use strict;
use Glib;

my $main_loop = Glib::MainLoop->new;

Glib::IO->add_watch (fileno 'STDIN', [qw/in/], \&watch_callback, 'STDI
+N');    

#just to show it's non blocking
my $timer1  = Glib::Timeout->add (100, \&testcallback, undef, 1 );

$main_loop->run;

sub watch_callback {
#    print "@_\n";
    my ($fd, $condition, $fh) = @_;
    my $line = readline STDIN;
    print $line;
    if ($line eq "q\n"){exit}
    #always return TRUE to continue the callback
    return 1;
}    

sub testcallback{
   print "\t\t\t".time."\n";
   return 1;  
}
__END__

or

#!/usr/bin/perl -w
use strict;
use Gtk2 -init;
use Glib  qw(TRUE FALSE);


Glib::IO->add_watch (fileno 'STDIN', [qw/in/], \&watch_callback, 'STDI
+N');    

Gtk2->main;

sub watch_callback {

    my ($fd, $condition, $fh) = @_;

        if(sysread(STDIN, my $buf, 1024)){ print "$buf\n" }
      
    #always return TRUE to continue the callback
    return TRUE;
}

or last resort put your stdin reading in a thread. Remember Gtk2 runs on Glib so this will work in a Gtk2 Mainloop as well. I use a Glib mainloop to show the simplicity.

#!/usr/bin/perl
use warnings;
use strict;
use Glib;
use Term::ReadKey;
use threads;

$|++;
ReadMode('cbreak');

# works non-blocking if read stdin is in a thread
my $count = 0;
my $thr = threads->new(\&read_in)->detach;

my $main_loop = Glib::MainLoop->new;

my $timer  = Glib::Timeout->add (1000, \&timer_callback, undef, 1 );
# can also have filehandle watches
#my $watcher;
#$watcher = Glib::IO->add_watch( fileno( $pty ), ['in', 'hup'], \&call
+back);

# must be done after main_loop is running
#Glib::Idle->add( sub{});
#print "$ps\n";

my $timer1  = Glib::Timeout->add (10, \&testcallback, undef, 1 );

$main_loop->run;

ReadMode('normal'); # restore normal tty settings

sub testcallback{
    my $ps = `ps auxww`;
    print "$ps\n";
    return 0; #only run once
 }

sub timer_callback{
     #do stuff
     $count++;
     print "\n$count\n";
    return 1;
}

sub read_in{
        while(1){
         my $char;
         if (defined ($char = ReadKey(0)) ) {
            print "\t\t$char->", ord($char),"\n";    
            #process key presses here
            if($char eq 'q'){exit}
            #if(length $char){exit}  # panic button on any key :-)
        
            if($char eq 'p'){
             Glib::Idle->add( 
                   sub{
                     my $ps = `ps auxww`;
                     print "$ps\n";
                     return 0;  # run only once
                   } );
               }
                
            }
          }
}
