Currently attempting to place the monitor into the background results in
an epoll error:
# ndctl monitor -b nfit_test.0
^Z
[1]+ Stopped ndctl monitor -b nfit_test.0
# bg
[1]+ ndctl monitor -b nfit_test.0 &
epoll_wait error
This error is simply a wakeup from a signal EINTR, so allow the monitor
to continue assuming the signal is not fatal.
