This was set up for me, and fiddling around with it pretty much led
me to the same conclusion. However, the question is---What motivated
this? Is it used by a large number of programs, does it have some

That is what I thought originally---However, whenever I Try and remove
that option from the kernel, programs like ps and w and others that
floating point die on flt pt exceptions. Does the world need to be
rebuilt?
