It also doesn't work on alpha and s390/s390x:

$ sleep 2 & sleep 1; ./strace -erestart_syscall -p $!
[1] 12345
Process 12345 attached
restart_syscall(<... resuming interrupted unknown ...>) = 0
+++ exited with 0 +++
[1]+  Done                    sleep 2

syscall number "unknown" is (surpise!) 516 on alpha and -516 on s390/s390x.
