overflow pdl /n./ [MIT] The place where you put things when
your pdl is full. If you don't have one and too many things
get pushed, you forget something. The overflow pdl for a person's
memory might be a memo pad. This usage inspired the following
Hey, diddle, diddle
The overflow pdl
To get a little more stack;
If that's not enough
Then you lose it all,
And have to pop all the way back.
--The Great Quux
The term pdl seems to be primarily an MITism; outside MIT this
term is replaced by `overflow stack'.
