[issue4336] Fix performance issues in xmlrpclib

[Jeremy Hylton]

Jeremy Hylton <jeremy at alum.mit.edu> added the comment:

Actually, the patch doesn't work :-).  The httplib API allows you to
pass a file or a string for the body of the request.  The
getheaderdata() + body case only works for the string.  Easy to fix,
but I worry that he still run into Nagle problems with the file case,
which was presumably added for efficiency.
