That is probably because we have only one global random state and many
packages reset it from time to time (see message-unique-id).
Why would extra invocations of (random t) cause repetitive behavior?
Ideally we should call (random t) only once or allow multiple random
states.
Supporting multiple random seeds would be a natural thing to do
if there is some advantage in sticking with one random seed
for a particular purpose, or if there is some harm in doing
(random t) extra times. But what reason could there be for that?
Except studying the pseudorandom number generator, that is.
