Now, maybe it can be made useful, but it tinkles all over the tcp fast path, requires maintenance, and I just don't feel like porting it forward to 3.1 or 3.2, or waiting for someone else to do so. In theory, it looked good. In reality, it's hard to care. I'm glad I tried it, I'm glad that it's out there and I could try it again, but I'd just as soon live without it. If jacobo has found a use for it, I'm all ears. --=20 Dave T=E4ht SKYPE: davetaht US Tel: 1-239-829-5608 FR Tel: 0638645374 http://www.bufferbloat.net
