Summary: Connect time not included in CURLOPT_TIMEOUT

Initial Comment:
Curl will not abort the operation until <connect time> + CURLOPT_TIMEOUT.

Testing this is a bit involved. I am using:
- The attached multi.php script which hits http://127.0.0.1:82/
- http://127.0.0.1:82/index.php which just sleeps
- The delay-net.pl from http://people.redhat.com/berrange/notes/network-delay.html with a 1.5 second delay
- To delay the initial connect the rule: iptables -I INPUT -i lo -p tcp -m tcp --dport 82 --syn -j QUEUE

Running multi.php then results in:
>php -f "multi.php"
Resource id #5: 28 (Operation timed out after 2000 milliseconds with 0 bytes received)
TotalTime: 3.5011 seconds

I gather this is not the expected behavior based on http://curl.haxx.se/mail/lib-2010-06/0087.html

I have yet to test this with a non php client (my c is rusty) but I have seen the same behavior with:
- curl 7.19.7 (ubuntu php)
- curl 7.20.1 (sabayon php)
- curl 7.21.1 (manual compile)

curl: (28) Operation timed out after 4000 milliseconds with 0 bytes
received
