[Python-Dev] stuck issue 26826

[Guido van Rossum]

Then again are people really concerned about the speed of those file
copy functions? Or are we just offering a solution in search of a
problem?

(I honestly don't know. At Dropbox we don't use Python for scripting
much, we use it to write dynamic web servers. Static files are served
by a CDN so e.g. sendfile() is not interesting to us either.)
