Querying INFORMATION_SCHEMA becomes slow in MariaDB 10.1

Querying INFORMATION_SCHEMA repeatedly using CentOS 6 becomes slow in MariaDB 10.1 (10.1.19, 10.1.24).

With a basic table, and simple repeated SELECT from I_S, on CentOS 6, thus far, we see a slowdown. It remains sub-second from my testing on Windows, even up to 2K iterations.

I will provide the CREATE TABLE and test case in a private comment.

Here are a sample of times from 10.1.19 (compared to times on MySQL 5.5 and 5.6) on CentOS 6.8:

MariaDB 10.1.19

real 0m16.970s

user 0m2.804s

sys 0m0.303s

MySQL 5.6.16

real 0m11.291s

user 0m2.331s

sys 0m0.280s

MySQL 5.5.36

real 0m7.246s

user 0m2.349s

sys 0m0.277s

And here are times from Elena (10.1.24 on CentOS 6.2) using test case provided:

real    0m4.699s

user    0m1.641s

sys     0m2.590s

This latter one is faster than the first one, but still not sub-second.
