I think good jj native hosting will push things off the edge form Git.
Snapshotting is a feature worth noting. You can capture a running VM’s state including CPU registers, memory, and devices, and restore it later. This enables warm pools where you boot a VM once, install dependencies, snapshot it, and restore clones in milliseconds instead of booting fresh each time. This is how some platforms achieve incredibly fast cold starts even with full VM isolation.

According to our push-based system, we update the first node in our graph (A). This pushes a signal to (A)’s dependents that they should now update. In this case, both (B) and (C) update. However, (B) depends on both (A) and (C), so when (C) updates, (B) needs to update again, and we discard any previous work we’ve done there. Similarly, based on just a single update to (A), (D) will receive three different signals to update.
