Потребление памяти nginx 'ом



Привет,

Наблюдаю интересную картину - после релоада nginx кушает в 2 раза больше памяти, рестарт/обновление бинарника возвращают потребление в норму.

Судя по http://www.lexa.ru/nginx-ru/msg16264.html, двойное увеличение потребления памяти должно быть только на время переконфигурации.
