Well, on MiNT, due to the lack of a virtual address space, the problem
is even worse as all memory regions attached to a process at the time of
the call to Pfork() have to be copied on each context switch that
activates one of the Pfork()ed processes when any of the others was last
active.

This gets even more worse with active memory protection, though I
discussed a way to bypass this (the slowdown with memory protection, not
the performance problem of Pfork() itself) with Frank on IRC this week.
It should make it into one of the next betas.
