Summary: curl cannot bind address when using --local-port

Initial Comment:
When using local-port to specify local port, the first connection correctly, but the second connection cannot bind address.
Such as:
$ curl http://httpserver/page --local-port 10000
then get right page, but run it again:
$ curl http://httpserver/page --local-port 10000
output:
curl: (7) bind failure: Address already in use

This is how the system works. A recently "binded" port cannot be used
again within a certain period of time.

Are you asking for SO_REUSEADDR to be used? I think that perhaps should
make sense and would then reduce this problem.
