Prevents premature EOFError on blocking reads

[hessammehr]

Blocks until the required number of bytes has been read. Only throws EOFError on actual EOF. Fixes #13559.

Travis failure is OOM killer. Can someone with the right permissions kick Travis now that #13577/#13621 are merged?

@pao Done.

[pao]

Thanks!

Changes to .travis.yml usually need a rebase to take effect.

Delete the now unused C function?

Oh. Right. Duh. My bad. From the branch name this looks like this was submitted from the GitHub editor. @hessammehr, you feel up to doing the rebase?

[tkelman]

A new commit to the same branch might also make Travis re-run the yml to sh conversion, I'm not positive. How Travis works can be subtle sometimes.

[pao]

This branch would be missing the commits which update the .travis.yml, though, right?

[hessammehr]

@pao The best I could manage was to point my master at patch-1, then rebase and open another pull request. I hope I didn't mess things up. The new PR is #13632.

[pao]

That'll work. Superceded by #13632, then.

[tkelman]

Travis might recompute for a new merge commit.
