preventing infinite loops

[user-74]

after code generation and before execution, we should inject some code that detects whether an infinite loop has been created, e.g. a max number of iterations/recursions, so we can break out of them and prevent the tab from crashing.

The repeat until / while blocks is the main point of concern here.

Good catch, @user-74 . this is important to do as well. and injecting code (max number of iteration) is the way to go.
