It was a _natural_ choice for me... (Well after i got really tired of
fighting my _first_ choice - AWK (when iconvert was still a throwaway toy)

I have tried running some demos with softmmu, it provides no noticable
benefit over hard one. If not pagefaults then constant translation block
generation/recycling will take its toll (but this probably covers mostly
real-mode or before watcom came into fashion p-mode programs, not that
i havent seen quite ingenious SMC in DOS4G/W applications)
