------------------------


Many testsuite tests use global variables to store information during the test
run. Sometimes quite large amounts of information are stored there, e.g.
monitoring data in the performance/throughput test.

The test template (checktree/test_template) foresees to destroy the global
variables in the cleanup function, but most tests don't do it yet.

A better approach would be to destroy the test global variables automatically in
the testsuite framework:
- before a check is started, get a list of all global variables (TCL function
"info globals")
- after the check get the list of all globals, and delete the newly created ones.

Once this is done, remove destroying the globals from the tests cleanup functions.
