+  Note that rusage fields will be zero when using the fiber scheduler path.
+* Added `rb_thread_call_without_gvl` for blocking calls so that other Ruby
+  threads can run while waiting.
+* Added `RB_GC_GUARD` to protect Ruby objects during blocking operations.
+* Replaced deprecated `RSTRING()->len` and `RSTRING()->ptr` with `RSTRING_LEN()`
