/* the boot census, latched at the shell's first frame and never
           re-opened: how many commands the app asked for before it had
           drawn anything, how many of those left in the shell's own turn,
           which kinds they were, and how long it took. A probe landing a
           second and a half later still reads the launch. -1 is "the census
           never sealed", -2 is "there is no census". bootCmds is the
           distinct names, not the whole run of them — every step carries
           it, and what is ever asked of it is whether a kind of command was
           at boot at all. */
