Does logging work with fifo?

- Subject: Does logging work with fifo?
I use the following command in the batch mode to print out the
backtrace information. /tmp/tmp.TNLBr685Zp is a fifo.
set logging redirect
set logging file /tmp/tmp.TNLBr685Zp
set logging on
While the gdb process runs in the background (via & in shell), the
fifo is catted (via the command cat) and piped (via pipeline '|' in
shell) to a following process for reading and processing the logging
output. However, it seems that sometimes it finishes prematurely. I
have no clue what the problem is. Could it be that logging does not
work well with fifo?
