First of all let me tell you how awesome is your regular testing, thank
you! It is helping a ton to deliver stable code :)

>From my point of view I think that you can attach gdb to one or more httpd
processes and do the usual "thread apply all", IIUC your httpd ends up
having all of its processes in more or less the same state right?

Let's use https://apaste.info/ or similar though otherwise we'll need to
exchange super long emails.

Thanks again!

Luca
