. Make cells get buffered on circuit, not on the or_conn.
- o Implement cell queues
- o Keep doubly-linked list of active circuits on each or_conn.
- o Put all relay data on the circuit cell queue, not on the outbuf.
- o Don't move them into the target conn until there is space on the
- target conn's outbuf.
- o When making a circuit active on a connection with an empty buf,
- we need to "prime" the buffer, so that we can trigger the "I flushed

- X Change how directory-bridge-choking works: choke when circuit queue
- is full, not when the orconn is "too full".
- [No need to do this: the edge-connection choking will already take
- care of this a bit, and rewriting the 'bridged connection' code
- to not use socketpairs will give us even more control.]
- . Do we switch to pool-allocation for cells?
- o Implement pool-allocation
- o Have Tor use it for packed cells.
- o Document it.
- o Do something smart with freeing unused chunks.
+ . Switch to pool-allocation for cells?
- Benchmark pool-allocation vs straightforward malloc.
- Adjust memory allocation logic in pools to favor a little less

anonymity implications.

- o Figure out how to ensure that handle_read is always called.

. Implement
- o Count connections and sockets separately
- . Allow connections with s == -1
- o Add a linked_conn field; it should get marked when we're marked.
- o Add a function to move bytes from buffer to buffer.
- o Have read_to_buf dtrt for linked connections
- o Have handle_read dtrt for linked connections
- o Have an activate/deactivate_linked_connection function.
- o Have activated connections added to a list on first activation, and

- o Handle closing connections properly.
- o Actually create and use linked connections.
- Handle rate-limiting on directory writes to linked directory
connections in a more sensible manner.
- o Rename want_to_read and want_to_write; they're actually about
