it looks like the diff won't apply as-is, but I think the concept still applies.

note that there have been a LOT of changes in libpthread since netbsd-9,
and some of those changes also claim to fix problems where threads hang
waiting on locks and/or condvars.  it would be more useful to test
with a HEAD libpthread (which I'll guess requires a HEAD libc too).
