Use of sequential addresses for heap allocations in Stack v. Heap documentation is somewhat misleading

[huonw]

In a typical long-running program that is performing allocations and deallocations as it goes, successive allocations are unlikely to be exactly adjacent in memory, but https://doc.rust-lang.org/stable/book/the-stack-and-the-heap.html may imply that there's more predictability than there is. That said, a normal allocator won't be completely unpredictable.

One suggestion from twitter was to use random numbers for heap allocs.
