Each Raindrops object is a container that holds several counters. It is internally a page-aligned, shared memory area that allows atomic increments, decrements, assignments and reads without any locking.
rd = Raindrops.new 4 rd.incr(0, 1) -> 1 rd.to_ary -> [ 1, 0, 0, 0 ]
Unlike many classes in this package, the core Raindrops class is intended to be portable to all reasonably modern *nix systems supporting mmap(). Please let us know if you have portability issues, patches or pull requests at raindrops@librelist.org
