Emacs in Daemon mode

When I started to use emacs as Java IDE, I have installed CEDET and JDEE. This make start time of emacs longer, even when I am not opening any Java file. Therefore, it is required to start Emacs in daemon mode. So that only one time startup is longer, and subsequent startup of emacs (emacs client to be precise) will be much faster.

I have written the following shell script (em, please place it in your $PATH), which starts the emacs daemon on first time only, and connects emacsclient to it.

#!/bin/bash

usr=$(whoami)
emacs_daemon="emacs --daemon"
cmd="ps auxww | grep \"$usr.*$emacs_daemon\" | grep -v grep"
#echo "$cmd"
is_running=$(eval "$cmd")
if [ -z "$is_running" ]
then
    echo "Starting emacs daemon"
    eval "$emacs_daemon"
    if [ $? -ne 0 ]
    then
        echo "$0: Cannot start $emacs_daemon" >&2
        exit
    fi
fi
emacsclient -a "" -t "$@"
exit $?

First Run:

$ em Hello.java
Starting emacs daemon

Warning: due to a long standing Gtk+ bug
http://bugzilla.gnome.org/show_bug.cgi?id=85715
Emacs might crash when run in daemon mode and the X11 connection is unexpectedly lost.
Using an Emacs configured with --with-x-toolkit=lucid does not have this problem.
