A Low-level Trampolining Facility in C & Assembly

1. Do I need a trampoline?

   Probably not.

2. But...?

   When you do, you really do.

3. What's it good for?

   This one, for manipulating the size of the execution stack at runtime.

4. Why would I want to do that?

   Because sometimes the default size is too small, blowing up under heavy recursion and/or large values.

5. How can I use it?

   That's an exercise left to readers at the moment.

6. Will that ever change?

   A higher-level C++ wrapper that allows setting the stack size of a standard library thread is in the works.

7. Meaning...?

   By default--and normally without recourse--instances of std::thread have a fixed stack size; worse, in the case of Apple platforms (notably iOS & macOS), that size is miniscule (512·KB as of this writing). Numerous people and projects have run into this limitation, especially when using functional code. This would provide a way to get around that problem--or jump past it, if you will.
