"The stack is nothing more than a chunk of RAM that stores data for use  by the processor.  As a program needs to store information, data is
pushed onto the stack.  In contrast, as a program needs to recall information, it is popped off the stack.  This method of updating the stack is known as first in, first out."

A stack is FILO, or First In, Last Out.  When you pop a value from the stack, you get the most recent value to have been  "pushed".

some advice on ~/.ssh locking

As long as ~/.ssh2(or ~/.ssh) directory is owned by a user, the user can remove the file "authorization"(or "authorized_keys"). So although the user cannot modify the file, he can remove the file and create a new file with the same name. It doesn't work for a skilled user.
