SVN rev 192125 on 2009-05-14 22:01:32Z by jhb
- Use a separate sx lock to try to limit the number of concurrent userland
sysctl requests to avoid wiring too much user memory. Only grab this
lock if the user's old buffer is larger than a page as a tradeoff to
allow more concurrency for common small requests.
- Just use a shared lock on the sysctl tree for user sysctl requests now.
