----
Prime numbers sieve implementations using CSP channels in Go.
----
./sieve1.go Taken from the Go language tutorial, worse than trial division
./sieve2.go Eratosthenesque, simple implementation
./sieve3.go Eratosthenesque, with wheel optimization and more efficient
implementations of `PeekChHeap` and `sendproxy`, the result is
about 4x faster than ./sieve2.go
