RELEASE SHOWSTOPPERS:
*) Looping during check_headers() failure.
+ Fix potential looping in new check_headers() due to new pattern of
+ ap_die() from http header filter. Also, remove the bad headers explicitly.
+ Trunk patch: https://svn.apache.org/r1773293
+ 2.4.x patch: trunk works
+ +1: covener, jim
+ -1: wrowe
+ covener: This is not ideal but the looping/OOM is bad.
+ jim: with the understanding that more work post release
+ wrowe: *IIUC* If we are transmitting the discarded body to the client,
+ and switching the code to 500, this isn't really a salvagable
+ resolution. Two alternatives suggested to the list a few days ago.
+ ylavic: how about r1773761?
*) Final CVE check
