and so i added it. But i hate doing that. Because such switch should not exist and VM should be able to adapt to application's memory requirements automatically, without requiring user's input.
I'm like you but I built a shield of pragmatism else I would have never started pharo :)
Because then you have to write manual, explaining what is address space, and why users should be educated about it in order to use VM properly.
But we should first make sure people can get money for project in Pharo and after I'm sure that we will get money to build the next generation.
And every other switch like this one you add, it makes manual bigger and bigger, up to the point, that it turns into complete mess of inter-depending, conflicting switches, some of them obsolete, some of them tricky and nobody knows how to use them properly (and that happens for sure).
But this is better than do not existing because people can not deploy professional applications with Pharo. Life is a tradeoff
