Kernel
Daemonize core_ext/kernel/daemonizing.rb
Normally, when a process is attached to a console and that console exits, the program
terminates. Kernel#daemonize is used to detach a Ruby process from the console, allowing it
to persist even if the console goes away. A typical daemon process will use daemonize as in
the following example:
# server setup; process options
daemonize # detach from tty
loop do
# wait for request
# process request
end
Sending SIGTERM to a daemonized process kills it.
Reporting core_ext/kernel/reporting.rb
The top-level methods in this file control console messages that might be displayed.

??? silence_stream(stream) silences the given stream (usually STDOUT or STDERR) for the
duration of the block.
??? suppress(*exception_classes) ignores errors of the specified classes during the execution
of the block.
