Depends who you ask. :-) Michael Hancock (sp?) has been doing some good stuff with cleaning up of the allocation and freeing of locks and resources, but there's more work to do still. You might find that the remaining warts will make life truely "interesting". There are a number of unresolved issues with the vnode locked/unlocked protocol as well as advisory file locking and directory cookies and readdir/lseek interaction etc. > Stephen Cheers, -Peter -- Peter Wemm <peter@netplex.com.au> Netplex Consulting To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
