asterisk users - Nov 2004 - safe_asterisk isn't auto-restarting

Here is how I start asterisk with safe_asterisk:

[asterisk@asterisk asterisk]# /usr/sbin/safe_asterisk 2>&1 >/dev/null
&
[1] 7514
[asterisk@asterisk asterisk]# 
[1]+  Done                    /usr/sbin/safe_asterisk 2>&1 >/dev/null
[asterisk@asterisk asterisk]# 
[asterisk@asterisk asterisk]# !as
asterisk -Rvvvvvvvvvvgn
<connects to asterisk console>

Yet, when asterisk crashes, safe_asterisk, doesn't restart it.

Any ideas?
