Revision 1d0671b81f18385ee6e73eed12b27fb25f27c67d authored by Dr. Matthias St. Pierre on 21 October 2018, 16:49:19 UTC, committed by Dr. Matthias St. Pierre on 26 October 2018, 06:50:26 UTC
Increase the load buffer size such that it exceeds the chunk size by a comfortable amount. This is done to avoid calling RAND_add() with a small final chunk. Instead, such a small final chunk will be added together with the previous chunk (unless it's the only one).
