Do you mean "-K16m"? Or do you mean heap space?
I'm interested in big stacks. Just occasionally GHC programs will die with
stack overflow, but don't if you make the heap *smaller*! The reason is that
the garbage collector also does a "stack-squeezing" trick that I have never
written up, so forcing a gc sometimes shrinks the stack massively. I'd be
interested to know if your prog is one of these.

Seems like a reasonable idea. But no, GHC doesn't have this mechanism.
