This is not a scheduler in the runtime, instead every goroutine is mapped to a single OS thread - meaning 1:1 scheduling. While this may not perform well (or at all) for large numbers of threads, it greatly simplifies many things in the runtime. For example, blocking syscalls can be called directly instead of having to use epoll or similar. Also, we don't need to do anything special to call C code - the default stack is all we need.
