Log message:
        Added MONIT_xxx environment variables to all programs executed by spawn.
        (also removed the dubious release memory code to make spawn simpler)
        
        The current environment variables are (with example values):
        
        (Which variables to use are absolutely open for discussion)
        
        MONIT_PROGRAM_CPU_PERCENT=0
        MONIT_PROGRAM_MEMORY=2332
        MONIT_PROGRAM_PID=12470
        MONIT_DATE=Wed, 18 Jun 2003 03:50:48 +0200
        MONIT_PROGRAM_CHILDREN=1
        MONIT_PROGRAM=/home/hauk/bin/tst
        MONIT_HOST=t7w7kz
        
        The above values is if a program was stopped, if it was started many 
variables
        have a null value, e.g. the pid is not set and so on. This means that
        many variables does not have much meaning in the usual case where monit
        starts a program. Should we drop variables? Viewpoints???
        
        To test I use a simple script that pops up an xterm. Here's the fake
        entry in .monitrc and below the script:
        
        check test with pidfile /tmp/tst.pid
        start program = "/home/hauk/bin/tst start -bg blue -fn 7x13eurobold"
        stop program  = "/home/hauk/bin/tst stop"
        host nettvenn.sol.no port 80 proto http
        request "/index.jhtml?action=user_create"
        alert address@hidden
        if cpu usage is greater than 10% then alert
        checksum /home/hauk/bin/tst
        group server
        host shop.sol.no port 443 type TCPSSL proto http
        timeout if 2 restarts within 3 cycles
        
        The script (remember to do xhost +localhost in the monit console first):
        
        #!/bin/bash
        
        /usr/bin/env > /tmp/myenv
        echo "Got $# argument(s): $*" > /tmp/myargs
        
        export DISPLAY=localhost:0.0
        
        case $1 in
        start) shift;
        echo $$ > /tmp/tst.pid
        exec 2>&1 1>/tmp/tst.log
        exec /usr/X11R6/bin/xterm $*;;
        stop)   shift;
        kill `cat /tmp/tst.pid`;;
        *)     echo "usage: tst {start|stop}";;
        esac
