I've been running it in a test rig to check = for wrapping and aliasing scenarios. I'll test it shortly. Note that it uses tcp-style sequence space signed arithmetic to handle wraparounds. The use of signed math is intentional. --=20 You are receiving this mail because: You are the assignee for the bug.=
