Use of saguaro stack for multitasking

The first documented use of a saguaro stack that I'm aware of was on the Burroughs B6500^[1]^[2], where the stacks for various tasks in a program formed a tree structure, with links to stack frames on the parent stacks for nested blocks.

What model does Smalltalk use?

We have an inconsistency I think. This page says:

Examples of languages that use spaghetti stacks are:
...

Languages where the execution stack can be inspected and modified at runtime such as Smalltalk

...and on the other hand, Closure (computer science) says:

Since that call has already returned and the Smalltalk method invocation model does not follow the spaghetti stack discipline to allow multiple returns, this operation results in an error.

I don't know enough about Smalltalk to tell which one is right. --Doradus (talk) 12:34, 20 October 2012 (UTC)[reply]
