I just did an experiment that suggests that's not the case.
I created a socket without SO_REUSEADDR, made a connection to
it, and killed it. Then I created another socket within the
timeout period with SO_REUSEADDR, and it succeeded.

This was on MacOSX -- it's possible that other systems
behave differently.
