netbsd-9 almost certainly has the issue that this latest patch
is trying to fix.  the patch above is just a one-liner and can easily
be adapted for netbsd-9.  but this patch alone is probably not enough...
there have been many changes to libpthread in HEAD since netbsd-9,
claiming to fix problems with the same kind of hang symptoms,
and some of those would almost certainly be needed in netbsd-9 as well.
I don't know for sure which of the changes from HEAD are needed,
so that's why I'm suggesting we just test with all of those changes,
ie. test the HEAD libpthread.
