Comment:

 I proposed to revert this is #22526 in favor of a simpler fix.

 The cache invalidation with static was introduced in r9102 with version
 2.7. Multisite wasn't in core back then, so something like
 `switch_to_blog()` wasn't a concern, but now it breaks if you switch the
 blog in between calls to `clean_term_cache`.

 [attachment:14485.2.diff] removes the static array. It only affects core
 bulk actions and plugins doing multiple calls to wp_term_* in a single
 request.
