=== Significant build performance drop on Windows for huge multi-projects

Another side effect of the snapshotting of individual class files, only affecting Windows systems, is that the performance can significantly drop when processing a very large amount of class files on the compile classpath.
This only concerns very large multi-projects where a lot of classes are present on the classpath by using many `api` dependencies.
