Original Alice wakes up from her write-full dream

• Original Alice eventually wakes up.
• If the cache had space - very quickly.
• If the cache had lack of space - then after some free space is made.
  • Creating this free space might require just throwing away cached items (e.g. read-cache)...
  • ...or it may require writing older cached writes back to disk - which is much slower.
• In some cases (that we'll see later on) - original Alice wakes up only after all Little and Big Alices finished their race.
