counting the number of connections?

Hi,

some time ago I noticed curl doesn't remember your credentials (apart
from those it can get from ~/.netrc), and very recently there was an
thread on repeated prompting for credentials while pushing to https.

I've written a simple patch series, which allows git to play nice
without curl_multi. That is, git uses a single persistent connection
throughout.

However, I'm at a loss at how to test for this. How does one count the
number of connections made during the lifespan of a program's
execution? So far, I've been relying on my firewall log (Comodo on
windows). Perhaps there a more operating system/software-agnostic
method to do this?
