// The events that affect the different RLZ scenarios are the following:

//  A: the user starts chrome for the first time

//  C: the user start a subsequent time
//  D: the user stops chrome again
//  I: the RLZTracker::DelayedInit() method is invoked
//  X: the user performs a search using the omnibox
//  Y: the user performs a search using the home page
//
// The events A to D happen in chronological order, but the other events
// may happen at any point between A-B or C-D, in no particular order.
//
// The visible results of the scenarios on Win are:
//
//  C1I event is recorded
//  C2I event is recorded
//  C1F event is recorded
//  C2F event is recorded
//  C1S event is recorded
//  C2S event is recorded
//  RLZ ping sent
//
//  On Mac, C5 / C6 are sent instead of C1 / C2.
//  On ChromeOS, CA / CB are sent, respectively.
//
// Variations on the above scenarios:
//
//  - if the delay specified to InitRlzDelayed() is negative, then the RLZ
//    ping should be sent out at the time of event X and not wait for I
//
// Also want to test that pre-warming the RLZ string cache works correctly.
