-# When this function returns:
-#
-# 1) The calling process is disconnected from its controlling terminal
-# and will not exit when the controlling session exits
-# 2) If a pidfile name is provided, it is created and the new pid is
-# written into it.
-# 3) If a logfile name is provided, it is opened and stdout/stderr are
-# redirected to it.
-# 4) The process current working directory is changed to '/' to avoid
-# pinning any filesystem mounts.
-# 5) The process umask is set to 0111.
-#
-# The return value is the new pid.

-#
-# Daemonized GNU Radio applications may be stopped by sending them a
-# SIGINT, SIGKILL, or SIGTERM, e.g., using 'kill pid' from the command line.
-#
-# If your application uses gr.top_block.run(), the flowgraph will be stopped
-# and the function will return. You should allow your daemon program to exit
-# at this point.
-#
-# If your application uses gr.top_block.start(), you are responsible for hooking
-# the Python signal handler (see 'signal' module) and calling gr.top_block.stop()
-# on your top block, and otherwise causing your daemon process to exit.
