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.
