Why do they end up in TIME_WAIT ?

What wasn't possible? Also, be careful about trusting specific information
"found over the net" if it is about libcurl details and doesn't come from this
mailing list or our documentation.

obvious ways you can do it with. But I would also persue the reason for this
situation in the first place and make sure there's nothing wrong that causes
it to trigger as then doing socket options would only hide the symptom and not
fix the real problem - if even that.
