 I ran the ltp tests (built on CentOS 7, which ships glibc v2.18 like the 
 pkgsrc suse13 packages))
 
 <ftp://ftp.causeuse.org/pub/NetBSD/kern-56828/ltp_futex.tar.gz>
 
 on netbsd-current (-10 userland, FWIW),
 
 <ftp://ftp.causeuse.org/pub/NetBSD/kern-56828/ltp-futex-netbsd-current.log>
 
 netbsd-9
 
 <ftp://ftp.causeuse.org/pub/NetBSD/kern-56828/ltp-futex-netbsd-9.log>
 
 and (FTFOI) freebsd-13
 
 <ftp://ftp.causeuse.org/pub/NetBSD/kern-56828/ltp-futex-freebsd13.log>.
 
 While the netbsd-9 run fails several tests that succeed on -current, the 
    futex_wake02 test succeeds on -9 but fails on -current.
