There are several things you can do to prevent a syscall from being stuck infinitely in Go:

1. Use a timeout: You can wrap your syscall in a function that uses Go's built-in time package to timeout after a certain amount of time. If the syscall takes longer than the specified time, the function will return an error.

2. Use a context: You can create a context with a timeout or deadline and pass it to the syscall. If the syscall takes longer than the specified time, the context will be canceled and the syscall will return an error.

3. Use a non-blocking syscall: Some syscalls have a non-blocking version, which returns immediately if the operation can't be completed without blocking. You can use this version of the syscall and check the return value to see if the operation was completed or not.

4. Use a separate Goroutine: You can spawn a separate Goroutine to handle the syscall and use a channel or context to communicate between the main Goroutine and the syscall Goroutine. This way, if the syscall gets stuck, the main Goroutine will not block indefinitely.

5. Check for errors: When using syscalls, always check for errors and handle them appropriately. Ignoring errors can lead to unexpected behavior and can cause the program to get stuck in a loop.
