History
mycroft 66418680d4 The reconnect algorithm was historically O(n^4). 
Some years ago I made it O(n^2).
Someone helpfully made it O(n^4) again.
Today I'm making it O(n).
If that's not good enough, I don't know what else to do.  B-)

Technical details:
* The graph traversal in propagate() is modified to be able to start from any
  point in the tree.  To handle certain exceptional cases, it is also modified
  to work in two passes, marking the tree with a special tag and then changing
  it to DFOUND.
* The reconnect case now modifies the child/sibling pointers and calls
  propagate() to propagate the connection state starting with the reconnected
  directory.

Pray that you never encounter a file system trashed enough for this to matter.
