[issue1792] o(n*n) marshal.dumps performance for largish objects with patch

[Facundo Batista]

Facundo Batista added the comment:

Why not just double the size? The "doubling + 1024" address some
specific issue? If so, it should be commented.

Also, do you have an example of a marshal.dumps() that suffers from this
issue?

Thank you!
