The returned pid is used in a sub which checks if the pid already exists. Due the fact, pack and unpack using the same template but returning different values this is a big problem. 

print pack    ('N', -3544)."\n";    # gives 'ÿÿò('
print unpack    ('N', 'ÿÿò(')."\n";    # gives '4294963752'

Shouldn't unpack return -3544 again?
