Oh, I forgot to mention the SHR. top says:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
12658 apache    15   0  535m  59m 8232 S    2  1.3   0:06.79 httpd              
17782 apache    15   0  406m  16m 3184 S    0  0.4   0:00.02 httpd              
18259 apache    15   0  531m  62m 8248 S    0  1.4   0:13.90 httpd              
12653 apache    15   0  536m  67m 8204 S    4  1.5   0:16.07 httpd              
 8455 apache    15   0  518m  48m 8008 S    0  1.1   0:01.62 httpd              
12653 apache    15   0  536m  67m 8204 S    4  1.5   0:16.19 httpd              
17780 apache    16   0  499m  27m 6064 R   12  0.6   0:00.36 httpd              

When I mentioned the 60/500MB usage I had top sorted by memory, so I
didn't see the 16m and similar low fat httpds. I guess the stats will
add up to the 32m mentioned below.
