Question about the return value of method `mi_page_extend_free(...)`

Does the following code should return `false` instead of `true`?

https://github.com/microsoft/mimalloc/blob/09a27098aa6e9286518bd9c74e6ffa7199c3f04e/src/page.c#L642

Which should signal the page extend failed?

Start with src/page.c at the linked line and inspect the callers of mi_page_extend_free(...) to understand how its return value is interpreted. Trace the success and failure paths, then verify that the returned boolean matches the documented or caller-expected outcome and run the relevant allocator tests, if available.
