An object is phantomly referenced after it has been finalized, but before its allocated memory has been reclaimed.

Famous quotes containing the words phantom and/or reference:
“Semi-Saracenic architecture, sustaining itself as if by miracle in mid air; glittering in the red sunlight with a hundred oriels, minarets, and pinnacles; and seeming the phantom handiwork, conjointly, of the Sylphs,... the Fairies,... the Genii, and ... the Gnomes.”
—Edgar Allan Poe (1809–1849)
“I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.”
—Carolyn Wells (1862–1942)
