Memory penalty. As busybox and dinstall are linked together in this
implementation, forking implies doubling the already big memory
requirements. Perhaps we should implement a libbusybox.so ...

(I wouldn't like to substantially modify busybox right now. We already
have enough work with the rewriting, and we need a set of working libc6
boot-floppies ASAP, but if someone wants to take care of busybox, he is
welcome).
