OpenBSD developers are making a serious effort to kill off indirect syscalls, the base system is completely clean, take a look at the work Andrew Fresh did to adapt Perl. He wrote a complete syscall "dispatcher" or emulator for the Perl syscall function so that it calls the libc stubs.

The ports tree is being cleansed of syscall(2) usage, until they're all gone.

msyscall, pinsyscall, recent mandatory IBT/BTI, xonly. OpenBSD is making some waves, but people aren't really seeing them yet.
