Failure caching assumes a CompileFailed is a function of
the sources, which is true for source errors. But zinc also surfaces I/O write
failures ("error writing X.class") as compiler problems, so an environmental
failure (a concurrent target/ deletion, a permission blip) was cached under the
same mechanism and replayed from the global action cache on every later build,
even after the cause was gone. When the poisoned task is the metabuild compile
this is self-sustaining and unrecoverable from inside sbt: project loading
fails, so no task -- including clean -- can run, and only deleting the global
cache by hand recovers. The replayed diagnostics also name files/permissions
that no longer exist.
