BSD and Darwin derivatives Fans of DragonFly BSD will be getting their Christmas present late this year, and plans for 1.5 have been announced. MP safe networking code, the long awaited cache coherency management system, and a port of Sun's ZFS. Read here for more. Update: Refresh, empty cache, whatever, and check the shiny new beastie icon! And there was much rejoicing. Can we now please discuss DragonFly BSD?

In what ways would it be "technically superior" to other operating systems?

Clustering, clustered filesystems, etc have been around
for quite a long time and operating systems like OpenVMS
and Linux are quite good at them.

SSI shared memory clusters are possible today with Linux
using a page based coherency protocol. I don't think
they're particularly practical because non-transparent
cluster software is really mature now and one actually
needs to program for a cluster in a non-transparent
way (far more important than even a slow NUMA) to get
decent performance.

However I'm not sure about what sort of SMP scalability
DFBSD would have if all code was fully MP safe using
LWKT as you say, nor advantages of XIO or ZFS.
