Playing devil's advocate here:
Aren't DB queries generally over TCP? Of course one should OPTIMIZE their DB queries,
but in many cases they're necessary in many cases, right?

Been there, done that :) async does not help in this scenario.
Killer here, as you mentioned, is wait, async moves the problem to the side only (learned
by testing)

YES! You've just summarised the central thesis about async that I made in this blog

TL;DR don't do HTTP queries from Kamailio. Just don’t
Well, you can set up a cluster of background workers and use the normal http_client. That
will speed up the process to read from the network as the network client processes are
freed up by you suspending the transaction and continuing in a background process (which
you need many of). This will make life better in some cases, but not all.
But in high volume, I would not _depend_ on any TCP-based external process, regardless if
it’s HTTP or databases.
