Dictionary.com/trampoline: “trampoline
n. An incredibly hairy technique, found in some
HLL and program-overlay implementations (e.g., on the Macintosh),
that involves on-the-fly generation of small executable (and, likely
as not, self-modifying) code objects to do indirection between code
sections. These pieces of live data are called `trampolines’.
Trampolines are notoriously difficult to understand in action; in
fact, it is said by those who use this term that the trampoline that
doesn’t bend your brain is not the true trampoline. See also snap.”
