This test expects that a library no longer being reachable along the import graph causes the library to be removed from the isolate's library list. The incremental kernel files used during reload don't really have a way to express this. The expected semantics also are a bit unsatisfactory. If a library is "deleted" this way, there may still be instances from library floating around, and re-importing the library would be treated like the addition of a new, unreleated library instead of modified the old library kept alive by those instances. Also, if an island of "deleted" libraries have static calls among themselves, those calls stop working because reresolving their targets fails because the "deleted" libraries aren't in the top-level namespace. The mistake of a global namespace continues to inflict damage.
