heavyweight: adj. [common] High-overhead; baroque;
code-intensive; featureful, but costly. Esp. used of communication
protocols, language designs, and any sort of implementation in which
maximum generality and/or ease of implementation has been pushed at
the expense of mundane considerations such as speed, memory
utilization, and startup time. EMACS is a heavyweight editor; X
is an _extremely_ heavyweight window system. This term isn't
pejorative, but one hacker's heavyweight is another's elephantine
and a third's monstrosity. Oppose `lightweight'. Usage: now
borders on techspeak, especially in the compound `heavyweight
process'.
