"504 Gateway Time-out"

Hector's original patch had very useful descriptions of the bug, why it
occurred, how it was exploited it and how the patch fixes it.

Your changelogs contain none of this and can be summarized as "randomly
churn code around for no apparent reason".

Wanna try again?  I guess the [0/5] and [4/5] changelogs are the ones
to fix.
