BIBI,

Lazarus was, as recounted in the New Testament, raised from the dead. The term "Lazarus" is, on occasion, place before something that was presumed gone forever, but has returned, and received with gratitude.

For example, in the game of foosball (often played in bars here in the States) the term "Lazarus ball" is applied to refer to an occasion when a ball is knocked into the goal, but pops back into play, rather than falling into the well underneath the playing surface.

Analogously, Cobalt's rescue of Pixies' Package #1, from the maw of the USPS brought it "back to life", and the return was welcomed by some of us.

Terribly sorry for confusing you, I had though the idiom was wider spread than it seems to be.
