I'm slightly worried about breaking 3rd-party code that might be using
recv() and somehow expecting the current behavior.  However, it's equally
arguable that such code would have Windows-specific problems that would be
fixed by the patch.  Now that we've seen a successful round of buildfarm
results, I'd be okay with back-patching 90e61df8 personally.

Any other opinions out there?
