In a deadlock situation both tasks are waiting for a resource that is 
held by another task, therefore none of the other tasks waiting for that 
resource can proceed. In TASK_INTERRUPTIBLE/TASK_UNINTERRUPTIBLE the 
task is in a sleeping state with the exception that TASK_UNINTERRUPTIBLE 
cannot be woken up by a signal. So it seems a deadlock can occur with a 
task in an interruptible or uniterruptible state.
