The direct chunk read opened one HDF5ImageSource::RawFile per file and never released it, so the
MAX_OPEN_FILES bound on the HDF5 handles did not hold for that path: a dataset stored one frame per
file would keep a descriptor per file open. They now follow the same least-recently-used bound; a
reading thread still holding a released handle keeps it through its shared_ptr.
