Bug Description

PyYAML includes a C implementation of the yaml parser. However, yaml.safe_load does not use it: for that you need to use yaml.load(..., Loader=yaml.CSafeLoader). As snapcraft always does the former, it's very slow for big yamls.

Granted big yamls should be avoided, but the performance difference is big enough to notice even in not-so-huge ones.
