  31  * FIXME:
  32  *
  33  *   - There is a race condition when two threads try to read from the same
  34  *     SMB handle. Either we need to lock the SMB handle for the time we
  35  *     use it in the client, or do all reading and writing to the socket
  36  *     fd in the server.
  37  *
  38  *   - Each new handle opens up a new connection to the SMB server. This
  39  *     is not ideal, since operations can be multiplexed on one socket. For
  40  *     this to work properly we would need to have some way of discovering
  41  *     connections that are already open.
  42  *
  43  *   - All access is currently anonymous. Password protected shares cannot
  44  *     be accessed.  We need some way of organising passwords, storing them
  45  *     in the config file, or putting up a dialog box for the user.
  46  *
  47  *   - We don't deal with SMB dialects at all.
  48  *
  49  *   - SMB supports passing unicode over the wire, should use this if possible.
  50  *
  51  *   - Implement ability to read named pipes over the network. Would require
  52  *     integrate this code with the named pipes code in the server, and
  53  *     possibly implementing some support for security tokens.
