1. [techspeak] During the execution of a procedural language, one is
said to unwind the stack from a called procedure up to a caller when
one discards the stack frame and any number of frames above it,
popping back up to the level of the given caller. In C this is done
with longjmp/setjmp, in LISP or C++ with throw/catch. See also {smash
the stack}.
2. People can unwind the stack as well, by quickly dealing with a
bunch of problems: "Oh heck, let's do lunch. Just a second while I
unwind my stack."
