/*
* Many operating systems allow signals to be sent to running
* processes. Some signals have a defined effect on the process, while
* others may be trapped at the code level and acted upon. For
* example, your process may trap the USR1 signal and use it to toggle
* debugging, and may use TERM to initiate a controlled shutdown.
*
* pid = fork do
* Signal.trap("USR1") do
* $debug = !$debug
* puts "Debug now: #$debug"
* end
* Signal.trap("TERM") do
* puts "Terminating..."
* shutdown()
* end
* # . . . do some work . . .
* end
*
* Process.detach(pid)
*
* # Controlling program:
* Process.kill("USR1", pid)
* # ...
* Process.kill("USR1", pid)
* # ...
* Process.kill("TERM", pid)
*
* produces:
* Debug now: true
* Debug now: false
* Terminating...
*
* The list of available signal names and their interpretation is
* system dependent. Signal delivery semantics may also vary between
* systems; in particular signal delivery may not always be reliable.
