Linux Daemon - Python sys.exit versus os._exit

Trying to daemonize a simple xmlrpc server i found some examples... let's give them credit:

W. Richard Stevens and Stephen A. Rago
Advanced Programming in the Unix Environment

Levent Karakas
http://www.enderunix.org/documents/eng/daemon.php

Devin Watson
www.netzmafia.de/skripten/unix/linux-daemon-howto.html

Chad J. Schroeder

Some of the examples suggested to use os._exit instead of sys.exit while daemonizing a process.
The difference is quite subtle and it's fully explained in two C man pages, Python implementation of these functions follow exactly what's defined here:

man 2 _exit
man 3 exit

They're not present by default in common desktop distros...
In debian they're in manpages-dev package; think is the same on rpm based distros (not sure).

Provo emacs per un po'

Ho sempre preferito vim ad emacs pero'...
...
mentre mi divertivo a studiare lisp/scheme sono stato costretto a confrontarmi con emacs...

...
non mi e' dispiaciuto per niente e ho deciso di provare ad usarlo per un po' come editor predefinito.
Ho fatto queste modifiche:

file: .bashrc

1. ho aggiunto un alias -> alias em='emacs - nw'
2. editor di default per le applicazioni da terminale -> export EDITOR="emacs -nw"
p.s. "-nw" serve per non avviare la versione X di emacs
