12914	Use yaml faster C implementation when available	Beuc	nobody	"pyyaml does not use the C implementation automatically.
Instead, it uses the Python implementation which is at least twice as slow.
This is one of the first thing that the documentation covers:
http://pyyaml.org/wiki/PyYAMLDocumentation#Installation

The attached patch uses the C implementation when available.

It would be nice to add a warning when the Python implementation is used, so that users are encouraged to install libyaml, but I'm not sure how to do it properly.
