Hrm, the setGlobalThreadCount() test crashes in a bizarre way in
libthr; I can only reproduce this with 7.0-BETA4 and 7.0-PRERELEASE
though. The whole test suite succeeds on 8.0-CURRENT and it also
doesn't crash when running a 8.0-CURRENT kernel with the 7.0
userland on the same machine, which suggests that some important
kernel fix in HEAD hasn't been MFC'ed, yet...

No; most likely because it's not implemented, see libpthread_md.c.
