Description:
As reported in Bug #69419 and also seen when doing a scratch build for Fedora 19, some tests may fail with a wrong result:

sys_vars.table_definition_cache_basic
sys_vars.table_open_cache_basic
table_definition_cache_functionality
table_open_cache_functionality

Filing a separate bug for the test issue.

How to repeat:
Run these tests on a *ix system where the open_files limit (ulimit -n) is 4096 or lower. At least fails on linux.

If open_file_limit >= 4161, the tests pass.

Suggested fix:
Skip the tests if open_files_limit < 5000
