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