- * sieve.c
- *
- * Finds prime numbers using the Sieve of Eratosthenes
- *
- * This implementation uses a bitmap to represent all odd integers in a
- * given range.  We iterate over this bitmap, crossing off the
- * multiples of each prime we find.  At the end, all the remaining set
- * bits correspond to prime integers.
- *
- * Here, we make two passes -- once we have generated a sieve-ful of
- * primes, we copy them out, reset the sieve using the highest
- * generated prime from the first pass as a base.  Then we cross out
- * all the multiples of all the primes we found the first time through,
- * and re-sieve.  In this way, we get double use of the memory we
- * allocated for the sieve the first time though.  Since we also
- * implicitly ignore multiples of 2, this amounts to 4 times the
- * values.
- *
- * This could (and probably will) be generalized to re-use the sieve a
- * few more times.
