Hello, This is a known issue, unfortunately. I brought it up recently (mailing list archives?) after I saw the same problems as you have.
I opted for your 3rd suggestion in my local version of HTTP Client. It is too early to put that in the distributed version of HTTP Client for now. As there is no intense development of HTTP Client that's worked fine for me. I simply used the Socket's connect call with some timeout value.
