destruction and VMVnodeCache::AcquireUnreferencedStoreRef(). Solved by adding a flag to VMVnodeCache and letting AcquireUnreferencedStoreRef() fail, if set. * Added TODO regarding replacing the snooze() waiting for busy vnodes. * get_vnode(): Unlock sVnodeMutex while calling the put_vnode() hook on error. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34841 a95241bf-73f2-0310-859d-f6bbb57e9c96
