Change all aux. buffers growing factor to 1.5. This is in general better in order to avoid heap fragmentation. When growing a buffer N times with the old factor of two (and when realloc() cannot just grow in-place), we create a gap 2^N-1 bytes long, but asking for 2^N bytes. This ever-growing hard-to-reuse gap can cause troubles to some heap allocators. See e.g. https://github.com/facebook/folly/blob/master/folly/docs/FBVector.md
