Go makes signal handling harder. Further, there is no FFI call overhead in Rust, C++, Swift. It isn’t marshalling, a function with no args will still incur an overhead.

Because Rust, C++ don't have a GC, while Swift does have a GC (RC is a GC algorithm) it was designed to be compatible with Objective-C runtime, thus C.
Having to swap stacks has not much to do with GC.
