I see at least one case where this can happen: pc_wait() returns a
message of type PC_SIGNAL or PC_BROKEN with uninitialized data and
length members, any nanny_exchangeVars() uses those uninitialized
values to construct messageOut, which it passes to cvt_buf2vars(),
which does a strchr() on the pointer and promptly dumps core.
