I guess most stack corruptions touch only a small part of the stack.
These kinds of corruptions can only be detected from inside the
program.

Anyway, going beyond the program's stack boundaries would fault the program.

Checking the threadinfo constantly it'll be (IMHO) mostly useless...

Can we just put a canary in the threadinfo and check it on every
task switch? What are the drawbacks?
