Ctrl-c handler isn't aware of what test is currently running. Because of that it executes all cleanups even if they aren't necessary. Since the ctrl-c handler uses the sa_sigaction system no parameters can be passed to it as function arguments.

These calls should have if (current_test->cleanup()) guard. Isn't the
Err, if (current_test->cleanup) is what I meant.
non-contiguous already test w/o the cleanup function?
Other than those two, this looked okay.
