- I'm not sure if this is what you are seeing, but pg 365 of "The Design and
- Implementation of the 4.3BSD UNIX Operating System", describes how 4.3
- BSD also starts the 2*MSL timer when in FIN_WAIT_2 state if the local

- It claims this is done as a work around because "certain other TCP
- implementations (incorrectly) fail to send a FIN on a receive-only connection.
- Connections to such hosts will remain in FIN_WAIT_2 state forever unless the
- system times them out".
