Agreed for this case, so feel free to merge your pull requests.

In the long term, I expect that all performance problems of 
information_schema will disappear (or at least that SHOW DATABASES is 
not faster...).

In bug #4243 the user is running MySQL 5.5. The last feedback I got from 
the admin of db4free.net is that he could not trigger information_schema 
performance problems, but he was running MySQL 5.6.
