Evgeny Vereshchagin f942504e4f basic: remove rm_rf_and_free, add rm_rf_physical_and_free, use rm_rf_physical_and_freep in tests (#3292)
Some distros don't mount /tmp as tmpfs.
For example:
https://lists.ubuntu.com/archives/ubuntu-cloud/2016-January/001009.html

Some tests:
* print 'Attempted to remove disk file system, and we can't allow that.'
* don't really cleanup /tmp
