Well blow me down, BrowserUK is correct. I've never gotten alarm() to work reliably on Windows - perhaps because I'm not that versed in Signals and didn't know what I was doing or was trying on a system call without the eval/die as described in alarm; however, alarm() added in my original script works:

use strict;
use warnings;

my $pid = open(my $fileHandler, '-|', "./test.exe" );

my $DONE = 0;
$SIG{ALRM} = sub { $DONE = 1 };
alarm 2;

while (<$fileHandler>) {
    print "$_\r"; # \r to not overrun output screen buffer
    last if ($DONE)
}

print "\nTimeout! - Time to kill pid: $pid\n"

And the output
