This is something I think about every time I deal with pycurl -- it
requires a real file object, not just a pseudo-file such as StringIO or
NamedTemporaryFile.  And I can see why the impedence mismatch between
pycurl and the underlying libcurl discouraged the pycurl programmers from
Doing The Right Thing.

So although I agree with you and although I get regularly annoyed at
pycurl, I am somewhat hesitant to cast stones as people who get it Wrong.

On the gripping hand, I am somewhat likely to discard pycurl if I get
enough tuits...
