Chapter 18: Memory and Variable Management 544
When you unarchive a variable, the Archive free amount increases immediately, but the
space is not actually available until after the next garbage collection.
If the
Archive free amount shows enough available space for your variable, there
probably will be enough space to archive it after garbage collection (depending on the
usability of any empty blocks).
