If a strong run_exports is present in the build section, any weak run_exports in the build section will not apply, because the strong run_export creates the host section with its injection of the strong run_exports.\r\n\r\nThis also switches from the yaml BaseLoader to the default.

Conda is not safe to run in multiple processes.  We do it anyway.  We try to use file locks, but conda still manages to mess up sometimes.  Both of the failures on appveyor and Travis are because of this, and thus they are not relevant to whether this PR was actually good to go."}}
