Worst case (may be different currently due to improvements in ipmi
stack) was about 10-15 minutes.

We have different issues on the SSH console though, we can end up
dropping chunks of console output under load (BMC CPU load or high
console usage).

I think Jeremy can relive the trauma of heading into the TTY layer, but
I wonder if the solution here has something to do with having a
end-to-end flow control story.
