We never see this in curl or other libcurl-using apps, which would indicate
that the problem is somehow PHP-related anyway.
Can you produce a libcurl-using source code that repeats the problem _without_
PHP? If so, then please post it. If you can't, then I'm not ready to deal with
it since PHP is a lot of code for a case that doesn't smell to be our fault in
the first place.
