@dysfun Out of curiosity, are you doing memory cleverness at the OS level, compiler/core library level, or userspace level? Because if you're at OS or compiler/core levels of the system you can do some Really Clever Things with the MMU that aren't phenomenally expensive...

@wordshaper not my paper.

i am only working in userspace.

@dysfun Pity. You can do fun things with even just the tiniest bit of access to the system hardware. (You also learn to swear at length and enthusiasm at Intel since their MMU hardware is... somewhat quirky and not necessarily as awesomely performant as one might want) It can make some of the generational copying algorithms a lot faster and you can make some of the transactional algorithms conceptually simpler if you squint right.

@wordshaper no good for the current project, but i'm certainly interested in hearing more

@wordshaper @dysfun And if you write UB, you can trap the nasal demons in your pentagram.
