Thats interesting.  I once did some quick and dirty profiling of vmtotal 
and found it runs extremely quickly.  Are you running on slow machines 
(embedded perhaps)?  Or do you have a situation where you perhaps have 
alot more VM objects created than normal?  I can't think of a good 
example where this would be the case..
