I still see some pthread related problems on my cobalt qube2 (mipsel)
after merge of the nick-csl-alignment branch: Some processes become
unresponsive after some time, e. g. /usr/sbin/named,
(pkgsrc/mail/clamav) clamd, (pkgsrc/security/amavisd-new) amavisd. I
can kill them only with 'kill -9 ...' and mostly (not always) can
restart them then. Reverting to src/lib/libpthread before this merge
make this problem go away.

Do you see any reason this (mis)behavior?
