 The function `wp_maybe_inline_styles` is called twice on templates. Hooked
 into `wp_head` and `wp_footer`. `wp_maybe_inline_styles` loops through all
 register styles to inlines them. But a the file operations, like
 `filesize` or `file_get_contents` can be expensive. On the first run,
 there should be some level or caching or flag set, to ensure that this
 function can be run multiple times without run the expensive file
 operations more than once.
