+/// This test creates a scenario to simulate what happens if hunks are loaded
+/// out of order. The compiler should initialize hunks in order regardless, but
+/// may do so in parallel while some hunks are not loaded yet.
+///
+/// To create a good number of hunks we created an import graph with 3 deferred
+/// imports and 7 libraries, we made pair-wise dependencies to be able to create
+/// 2^3 (8) partitions of the program (including the main hunk) that end up
+/// corresponding to the libraries themselves. In particular, the import graph
+/// looks like this:
+///
+/// main ---> 1, 2, 3 (deferred)
+/// 1 ---> 4, 5, 7
+/// 2 ---> 5, 6, 7
+/// 3 ---> 4, 6, 7
+///
+/// So each library maps to a deferred hunk:
+/// library 1 = hunk of code only used by 1
+/// library 2 = hunk of code only used by 2
+/// library 3 = hunk of code only used by 3
+/// library 4 = hunk of code shared by 1 & 3
+/// library 5 = hunk of code shared by 1 & 2
+/// library 6 = hunk of code shared by 2 & 3
+/// library 7 = hunk of shared by 1, 2 & 3
+///
+/// In the future we may optimize and combine hunks, at that point this test
