please ignore my ignorance but shouldn't one add this commit regarding 
src/doveadm/client-connection-tcp.c ...

https://github.com/dovecot/core/commit/2a3b7083ce4e62a8bd836f9983b223e98e9bc157

... to a vanilla 2.3.1 source tree as well?

I do have to admit that I am absolutely clueless in understanding 
dovecot's source code, but I came accross this commit because it has 
been committed the very same day as the one solving those hanging 
processes.

I could test it by myself, but I am not sure if that commit would break 
my productive dovecot instances.

Regards,
Michael
