Jon Siwek commented on BIT-1266:
--------------------------------

I haven't reproduced the problem exactly, but I was monitoring the behavior of -Bmain-loop for various commits and noticed a significant difference that might be due to a (unintended) difference in iosource::Manager::FindSoonest's fd_set construction -- quickly hacking out my FD_Set wrapper returned things to "normal".  Still in process of figuring that out, but thought I'd mention it since that change wasn't specific to the PktSrc reorg.

> Current master drops significantly more packets than 2.3. Looks like it's the packet source reorg: going back to 3caecadf0a3028e1dad7f446a92ffb7560c9a734 lets drop rates go back to normal.
