[-- Attachment #1 --] Hi Folks, Please could the wisdom-of-crowds apply its collective attention to this? Thanks!

In follow-up discussions, I will work out how to do this properly. Right now, that code works, but will no doubt piss off RWatson and company for messing up the carefully optimised slab allocator! :-) > > In the first merge, very little change should be observed. ‘sysctl kern.random’ will look different as the harvesting has been slightly generalised. Yarrow will still be used, but Fortuna will be available as an alternative.
