This incomplete patch adds a new filter allowing more control over
when nbdkit exits. You can now get nbdkit to exit gracefully on
certain events, such as a file being created, a pipe held open by
another process going away, or when another PID exits. There is also
a script option to allow for completely custom events.
It is untested at the moment, I'm posting it to get feedback on the
idea. The manual page is a complete description of the proposed
feature.
To do:
- implement the polling thread
- add tests
