Constrain the amount of kernel memory used by NTFS. Keep a small cache of
loaded ntnodes and once the maximum is reached, unload the least recently
used ntnode before loading a new one. This avoids leaving large data
structures hanging around, which only get cleaned up when the vnode is
reclaimed. Additionally, the buffer cache should contain the data needed
to reload the ntnode.
