Thomas Schoebel-Theuer e7f88c84d6 infra: rewrite brick_say to work with threads 
It was cumbersome to write to files in / after in_interrupt() & co.
A master write thread will also reduce the peak IO parallelism
on log data in /mars .

Further work has to be done to utilize non-default write channels.
