[issue31993] pickle.dump allocates unnecessary temporary bytes / str

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

As for the C pickler, currently it dumps the whole pickle into an internal buffer before calling write() at the end.  You may want to make writing more incremental.  See Modules/_pickler.c (especially _Pickler_Write()).
