The signal is often received during epoll_wait call, and python code later

sighandler, causing errors to be detected after the call (epoll_wait would
return -1 as the call was interrupted by the signal).

Disabled by default, as it allows code injection in NEO processes to
anyone with the ability to send signals to them and either write access to
NEO product or its controlling TTY.
