* Added a "canWait" argument to vfs_get_vnode() - you can use this to ignore

busy vnodes.
* dir_create_entry_ref() used get_vnode() incorrectly (and could therefore
  potentially prevent a file system from doing proper locking when called
  from the kernel).
* The vnode_store now uses this for its acquire_unreferenced_ref()
  implementation (and therefore for the page writer).
* read_into_cache() and write_to_cache() were still marked inline.
* The system will now wait 10 secs for a busy vnode before returning an error.
* It will also no longer panic in that case.
