Sigh. I initially had this exactly backwards: the object needs to be locked, the vnode does *not*. Avoids panic: locking against myself quickly reported by Charles.

a507fda378
vnode_pager_sync bugs: A) must lock the object, not just the vnode. B) Don't remove the object from paging queues, because we'd have to put it back on one. The pagedaemon will eventually take care of this for us anyway. This was causing us to *lose track of pages completely* every time vnode_pager_sync() was called... sigh. Credit goes to mycroft for untangling this mess.
