For my particular test case, yes. However, I don't recall ever
seeing vnlock dead locks when running the test program. Perhaps
we are seeing two different bugs?
FWIW, I even compiled apache2, with the --with-mpm=worker
settings instead of the default --with-mpm=prefork, and I could
run the web server as
env PTHREAD_CONCURRENCY=2 /usr/pkg/etc/rc.d/apache forcestart
and at times see 10s of LWPs per apache process. So, from my
perspective the new trap.c is a giant step in the right
direction.
