This test is very basic :( Need more work on it. One note about --close arg to crtools -- bash leaves all fds open when laucnhing progams, and for restore this is critical, as one of them can be busy. Iterating over all the possibel fds and closing them is "do not want" thing. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
