The cvsup mirrors don't seem to carry r242601 yet, so I just applied the r242601 diff that went to svn-src-all@ on top of whatever my cvsup mirror carries. I let curl request the 90000k file ~1000 times directly from gatling, ~1000 times from gatling using Privoxy as proxy and additionally executed ~900 Privoxy regression tests (which rely on TCP/IP and fail in case of incomplete transfers). Everything seems to behave like it should again.
