Выяснить, почему так много открытых pipe (нет ли утечки)

Выяснить, почему так много открытых pipe (нет ли утечки).
Особенно при перезапусках. А то иногда бывает так:

In 1099/sw:

Устранен баг: при рестарте swd новый процесс наследовал открытые файловые дескрипторы от старого,
в результате происходила утечка труб: с каждым рестартом число открытых процессом pipes увеличивалось
приблизительно на сотню. Одним из эффектов от этого были проблемы с загрузкой обновлений. Fixes #55.
