I haven't checked, but I assume that it makes the changes one at a time,
and then fails a consistency check. When it fails, anonmin is 80 and 
filemin is 10, so execmin can not be more than 5, as the sum of the 
minimums can not be grater than 95. I guess. :)
(See src/sys/uvm/uvm_meter.c UPDATEMIN macro definition)

So, try setting vm.file* first, then vm.exec* and finally vm.anon*.

The previous run successfully reduced filemin, so now you can set
execmin up to 14. I guess. :)
