Sure, this would be better I wasn't thinking straight when I did this
and had some spurious idea in my head why this wasn't possible. 

Also, I think that I'm suffering from some amnesia wrt the parameter
system - is the parameter "solver", set by

	pde.set("solver", "direct");

local to pde, and

	set("solver", "direct");

global?
