I still see it on an 11.0 BETA from Aug. 27 on hppa:

is this still a problem?  i switched us to using liburcu-mb which
avoided similar issues for me on arm64 a couple of weeks ago and
i am hoping this is the same underlying issue.

(there is some real bug here, that liburcu-mb avoids, but as the
memb version adds only overhead for netbsd, there's no reason
to use it, even when we fix the real bug.)

thanks.
