More debuging to heap tables.
Small cleanups to multi-table-delete

  Make copies of all string-type start/up options in case C-sharp moves them around; remove the need to specify innodb_log_arch_dir in my.cnf, since it has no relevance anyway

   ("comment" test failed when MySQL version was changed from 4.0.5
