(&self, error_code: usize)

    /// Note: Should only be applied to threads that
    /// will return from a syscall.
    pub fn return_error(&self, error_code: usize) {
        // Ensure that the error is in range, no message
        self.context_mut().rax = error_code &
            syscalls::SYSCALL_ERROR_MASK;
    }
