OK, I tried

# ps -e --no-headers -o vsz,cmd|grep httpd| wc -l
111
# ps -e --no-headers -o vsz,cmd|grep httpd|(j=0; while read i c ; do j=`expr $i + $j` ; done ; echo $j)
40752756
# ps -e --no-headers -o rsz,cmd|grep httpd|(j=0; while read i c ; do j=`expr $i + $j` ; done ; echo $j)
3569776

So it's about 32MB/360MB real/virtual just as you said in the beginning.
