punkish, It seemed to work for me. I used sc to do the install. Here is the script I registered along with a transcript of what I did after the __END__: 

use Win32::Daemon;

# print LOG "hello\n";

BEGIN {
  open( STDERR, ">>myservicelog.err" ) or die "invisible error";
  warn "$0 started ".localtime().$/;
}

open LOG, ">>mylogfile.txt" or die;

# Start the service control loop
Win32::Daemon::StartService();
while( SERVICE_STOPPED != ( $State = Win32::Daemon::State() ) ){
    if( SERVICE_STARTING == $State ) {
        # some service startup code
#        ......
        Win32::Daemon::State( SERVICE_RUNNING );
    }
    elsif( SERVICE_PAUSE_PENDING == $State ) {
        Win32::Daemon::State( SERVICE_PAUSED );
        next;
    }
    elsif( SERVICE_CONTINUE_PENDING == $State ) {
        Win32::Daemon::State( SERVICE_RUNNING );
        next;
    }
    elsif( SERVICE_STOP_PENDING == $State ) {
        # some service shutdown code
#        ............
        Win32::Daemon::State( SERVICE_STOPPED );
        next;
    }
    elsif( SERVICE_CONTROL_SHUTDOWN == $State ) {
        # Request x seconds to shutdown...
        Win32::Daemon::State( SERVICE_STOP_PENDING, 45 );
#        ..............
        Win32::Daemon::State( SERVICE_STOPPED );
        next;
    }
    elsif( SERVICE_RUNNING == $State ) {
        doMyStuff();
        print LOG "DONE!\n";
        sleep 3;
    }
    else {
        # Un-handled control messages
        Win32::Daemon::State( SERVICE_RUNNING );
    }
    sleep 5;
}
Win32::Daemon::StopService();

sub doMyStuff {
  print LOG "hello\n";
}

As I suspected, LOG is being buffered. So it didn't show up until after I stopped the service.

Hope this helps.

"Look, Shiny Things!" is not a better business strategy than compatibility and reuse.
