Still, a special case for automatic transmission of string arguments might make sense. open/stat calls are probably 90% of security-related calls and special-casing their arguments might give a sizable performance benefit.

File paths?

I wonder if anyone has gathered statics on syscall distribution for various types of workload?

I suspect that `statfs()` and `access()` are also frequent syscalls with string params. File distribution programs, such as HTTP servers, can produce a fairly extreme number of `access()` calls.
