Erreur: «fork: impossible de réserver de la mémoire au parent…» lors de l'exécution d'un programme Ruby dans Aptana Studio 3

Je reçois cette erreur chaque fois que j'essaye de lancer un programme simple écrit en Ruby:

Mon problème a été résolu après la mise à jour vers la dernière version de Cygwin. Je ne suis pas sûr du problème, mais la mise à jour de Cygwin a résolu le problème.
