Hello.
Cryptsetup version 1.7.0 and 1.7.1 gets stuck on luksOpen and luksClose
immediately after the device has been opened or closed.
The process has to be killed.
Here are the last bits of the strace output for luksOpen (after
entering the passphrase):

The device is closed correctly, however the cryptsetup process has to
be killed again to get the shell prompt back.
Previous versions (such as 1.6.8 and earlier ones) are not affected by
this bug.
Any idea ?
