-------------------------------------------------

For me it really does not matter now - I have dropped idea to migrate to 4.x altogether. Anyhow
it may be worth mentioning somewhere that such migration may cause unexpected issues.

> I have tried  benchmarks from httpclient-benchmark - results are some what funny - while
for most tried sites 4.0.1 is marginally faster then 3.1, for a couple of sites it is significantly
slower, the most noticeable for www.google.com, test were repeated multiple times, here are
sample output from 4.0.1 and 3..1
