The number of buckets is currently limited to ~2^32 (see X<>::primes). This is
a serious issue: for correctness, rehash(n) for n > 2^32 should throw and do
nothing, in order not to violate the post-conditions in Table 21.
We have various options: as suggested by Howard off-line, we could well compute
at run-time prime-numbers. Otherwise, mid-term, if we cannot extend the maximum
number of bucket we have to add throws to the rehashing functions.
