73 : 32 + (102 * sizeof(fd_vote_lockout_t)) = 1644 bytes.
74 :
75 : The worst case vector of fd_lockout_offset_t is one where each

79 :
80 : The deque of slot numbers is a vector of ulong, which is 8 bytes.
81 : So the worst case is 1232 bytes/8 bytes = 154 elements. So, the

83 :
84 : The worst case char vector is 1232 bytes as each element is 1 byte
