"man fifo" is not clear enough about this matter. The question is:
where is the limit? Is it a block of 4096 bytes? Is it the 0x0a char?
I just write lines no longer than let's say 80 to 100 charachters
(including the timestamp) so I presume there will be no problem.

And how would you merge two outputs from two separate multilog
processes into file. Using a postprocessor?

I could also use "setlock" to lock the fifo for writing.
