Safely remove a limited number of items from the cache_form table. This module provides a drush command drush safe-cache-form-clear that can be run at a high frequency, keeping the table at a reasonable size.

This module works around this by limiting the number of items expired from the cache in a single run, dealing with a single manageable chunk at a time.

BigPipe is a fundamental redesign of the dynamic web page serving system.
