So, it dies. I tried it a couple of times, with different media.
What is interesting - there are 2 cdrecord processes while burning.
# fuser -v /dev/sr0
                     USER        PID ACCESS COMMAND
/dev/sr0:            root      10330 F.... cdrecord
                          root      10342 F.... cdrecord
$ ps auxww |grep cdrecord

Note status of processes:
DL+    uninterruptible sleep (usually IO), etc
S+      interruptible sleep (waiting for an event to complete)

I googled and found a post by Jörg Schilling (cdrecord author), in response to above error lines,
that it is about some other app or process trying to acccess /dev/sr0 while cdrecord does too.
So I stopped udisks service
# systemctl stop udisk
that gave me this log entry approx around time I run cdrecord first time (it accessed /dev/sr0 and it could be
a suspect then, but not this time)

I also noticed that my xterm (from which I executed cdrecord) was locked up (could  not switch or open tabs).

I tried with XFCE's Xfburn, with the same result.
What is going on ?

Re: [SOLVED] cdrecord fails to burn iso on cd-r disk

Solved.
It was trivial: I cleaned the drive twice with a  special kit.
