After beating my head against the proverbial wall programmatically creating and deleting content with custom fields, this one has me scratching my head.
v7.26 - why is it *assumed* 'comment' is installed?
If I am wrong and it's not, then why are the variable_del('comment_' lines there?

I was unable to find any issue reports with Drupal core regarding this, and the documentation is not terribly clear. All of the documentation regarding variable_del and COMMENT_NODE_OPEN lead me to these conclusions. Clarity would be appreciated.
