11106 :: What will happen if allocation fails?

  It's well-known that a (heap memory) allocation can fail if the system has run out of memory and has no swap space available. So, what will happen if a call to new or alloc fails to do so?

  A MemoryDefect or a panic I'd imagine

  OutOfMemDefect is raised. There is also system.outOfMemHook that you can set.

  So a ref returned by new, or a ptr returned by alloc (or allocShared, or create, or similar), is never nil?

  Correct.
