----------------------------------
Summary: Improve reaper responsiveness on Linux
Key: MESOS-8166
URL: https://issues.apache.org/jira/browse/MESOS-8166
Project: Mesos
Issue Type: Bug
Reporter: James Peach
The {{ReaperProcess}} polls at a dynamic interval to determine whether any of
its monitored PIDs have exited. In the common case of a child process exiting,
we should be able to improve its responsiveness by using
[signalfd|http://man7.org/linux/man-pages/man2/signalfd.2.html] to catch
{{SIGCHLD}} and immediately reap any exited processes.
