Consider exponential growth in an oasis. If the colonists divide up the
oasis in proportion to the size of their colonies, then if the first probe
arrives many doubling times before the second, the result is nearly the
same as if the second probe never arrived. So if the frequency of probe
arrival is low compared to doubling times, it is a reasonable approximation
to neglect competition over oases, and just model oases as being given
totally to the first to arrive.
