Hey, hang on... the SMP problem shouldn't occur since only one
processor can own a process at any one time, so you don't need to
invalidate the TLBs of the other CPUs (which is what makes it suck.)
This is different from using virtual-memory allocations to grow the
process stack.
NOW, what is dangerous with it is that you must NEVER dereference
pointers to automatic variables for another process... those variables
simply will not exist in your new process context...
