We want a helper class to make it easy to implement a daemon.

Close all open file descriptors (especially standard input, standard
output and standard error)
Change its working directory to the root filesystem, to ensure that
it doesn't tie up another filesystem and prevent it from being unmounted
Reset its
umask value
Run in the background (i.e.,
fork)
Disassociate from its process group (usually a shell), to insulate
itself from signals (such as HUP) sent to the process group
Ignore all terminal I/O signals
Disassociate from the control terminal (and take steps not to reacquire one)
Handle any
