  "message": "Remove a level of indirection when using CellInfo\n\nThe CellInfo struct contains a mutex, which interacts poorly\nwith some standard library containers which may move things around.\nAs a result we were using std::unique_ptr\u003cCellInfo\u003e in these\ncontainers, but this change gets rid of that level of indirection\nas std::unordered_map can construct CellInfo in place and we can\nreplace the use of std::vector with an array we know will not be\nresized.\n\nThis improves the performance of the schur eliminator a bit but\nalso the performance of the block diagonal preconditioners.\n\nChange-Id: If3ccd1273a754d9c5112e6e611ce31066b6b27b5\n",
