Interesting. Could you summarise what the application/kernel is doing
here exactly? There are only a few syscalls we allow to be called out
of the kernel, and they only seem to be used during boot.

extern pid_t setsid(void);
extern int write(int fd, const char *buf, off_t count);
extern int read(int fd, char *buf, off_t count);
extern off_t lseek(int fd, off_t offset, int count);
extern int dup(int fd);
extern int execve(const char *file, char **argv, char **envp);
extern int open(const char *file, int flag, int mode);
extern int close(int fd);
extern pid_t waitpid(pid_t pid, int *wait_stat, int options);
