two major reasons driving it:
1. fips certification that curl has when linked to nss - urllib/m2crypto
doesn't have it

2. dealing with http proxies and accessing https sites - urllib can't
really do it - curl can.

minor reasons:
- all devel on urllib is pretty much stopped - if we want things fixed we
either havs to abstract them and fix it or we have to get the fix into
upstream python which can be time consuming.

- to see if it was doable or not.

- multi-file download support. - I've not implemented that yet to
CurlMulti() but it is part of a plan.

Thanks,
