http: handle push of bundles > 2 GB again (issue3017)
It was very elegant that httpsendfile implemented __len__ like a string. It was
however also dangerous because that protocol can't handle sizes bigger than 2 GB.
Mercurial tried to work around that, but it turned out to be too easy to
introduce new errors in this area.
With this change __len__ is no longer implemented at all and the code will work
the same way for short and long posts.

if os.path.exists('foo'):
os.remove('foo')
file = atomictempfile('foo')

assert not os.path.isfile('foo')
assert basename in glob.glob('.foo-*')
file.write('argh\n')
file.rename()
assert os.path.isfile('foo')
assert basename not in glob.glob('.foo-*')
print 'OK'
# close() removes the temp file but does not make the write
# permanent -- essentially discards your work (WTF?!)
def test2_close():

# get a plain ordinary TypeError, not infinite recursion
