O handler oomd est\u00e1 sendo desenvolvido pela empresa Facebook, cujos funcion\u00e1rios tamb\u00e9m est\u00e3o trabalhando em uma subcomponente do n\u00facleo chamada PSI (Pressure Stall Information), permitindo que o handler de falta de mem\u00f3ria no espa\u00e7o do usu\u00e1rio analise informa\u00e7\u00f5es sobre o tempo de espera para obter v\u00e1rios recursos (CPU, mem\u00f3ria, entrada\/sa\u00edda) para uma avalia\u00e7\u00e3o precisa do n\u00edvel de carga do sistema e do tipo de desacelera\u00e7\u00e3o no desempenho.<\/p>\n

O oomd est\u00e1 na fase final de cria\u00e7\u00e3o de um produto universal, adequado para qualquer carga de trabalho sem necessidade de ajuste adicional. Depois que os \u00faltimos componentes ausentes da interface PSI (\"iocost\") forem adicionados ao n\u00facleo do Linux, a empresa Facebook pretende transferir o oomd ou uma vers\u00e3o simplificada dele para inclus\u00e3o no systemd. Espera-se que isso ocorra dentro de seis meses a um ano. O Earlyoom pode ser utilizado no Fedora como uma solu\u00e7\u00e3o tempor\u00e1ria at\u00e9 que o oomd esteja devidamente ajustado, mas, a longo prazo, Potters acredita que o futuro pertence ao oomd.<\/p>\n
