Go rawVforkSyscall: Efficient Process Creation with Memory Sharing

The rawVforkSyscall function in Go is a low-level system call used to create a new process more efficiently than the traditional fork system call. The 'vfork' system call resembles 'fork' but shares the parent process's memory space until the child process calls 'exec' or 'exit'. This allows the child process to execute faster and more efficiently, as it doesn't need to copy the entire parent process's memory space.

The rawVforkSyscall function accepts a pointer to a syscall.RawVforkSyscall structure containing the arguments for the 'vfork' system call. The structure has three fields: a pointer to the child process ID, a pointer to the parent process ID, and a set of flags controlling the 'vfork' call's behavior.

The function returns an error if the system call fails or nil if it succeeds. It's crucial to remember that the 'vfork' system call isn't supported on all platforms and should be avoided unless absolutely necessary for performance reasons. Additionally, exercise caution when using 'vfork', as it can lead to unexpected behavior if not used correctly.
