Exactly what you said yourself. Code that inadvertantly keeps memory
around. Heavy use of symbols (in the sense of memoized strings) is
probably the easiest way to leak memory. Just about anything that is
linked to a a global data structure is a good candidate for leaking
If the garbage collector thinks your program could possibly ever use a
piece of memory again, it will not free that memory. The collector is
way more conservative than your brain, so it is certainly possible to
fool yourself about whether or not you *intend* to use data when you
have in fact kept it around.
