Binary fdmap looks... quite ugly to me. But close_all(from, to)

Given that openbsd has something similar... perhaps we can take that?

closefrom() can be implemented on top of fdmap().
fdmap as is is useful for other purposes.

Except during startup, application should have good idea what fds it
has open, so maybe that's enough?
