Comment(by metux):

 ''Comment from Miguel (on the list):''

 Opening the console in non-blocking mode is a bad idea,
 as it means that every call that is done later on the
 console_fd needs to check for EWOULDBLOCK. Most of the time,
 it would be not return that, it would
 only return that under
 unique situations which means that testing this
 patch would
 not only be non-trivial, but someone would have to audit
 all the code paths.

 Also, this is lacking a ChangeLog explaining why this is needed.

 But I think that this patch should not be applied, it seems
 like a workaround that has not been properly implemented.
