Further 2.00 work Testconfs in all supported kinds of archives should now work. Test runs are now cancelled by pressing Escape rather than Ctrl+C. Improved time control. Greatly improved temporary and helper file cleanup. The pause configuration variable can now be a callable and is now processed using subprocess rather than system().
