TODO:

- fix reported random crash
  . could not reproduce yet
  . maybe fixed in 0.16 SIGPIPE change?
  . some reports suggest this was fixed in 0.16 (not sure though)
- program reported to choke under load
  . could not reproduce yet
- improve bind-addr config syntax
- non-forking version with support to forwarding port ranges?
- save master-process PID to a file
- support for generic IP forwarding (IPfwd-style)
- close sockets before exiting on SIGTERM
- transparent proxy for linux kernel 2.4.x
- passive ftp support for linux kernel 2.4.x
- Marc Merlin suggestions:
  - Transparent proxy control per ruleset.
  - Issue fatal errors to stderr.
  - Try to bind to local address multiple times (specified by user).
- option to specify range for local source port of
  outgoing sockets; this is useful for services like
  lpd, which expects connections from ports within range 721-731
