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

[Antoine Pitrou]

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

Agreed.  We shouldn't issue very small writes, but 64 kB is generally considered a reasonable buffer size for many kinds of I/O.

Besides, it wouldn't be difficult to make the target frame size configurable if a use case arose for it, but I don't think we've ever had such a request.
