I wish I could, but I know nothing about it. Anyone else?

Wait! Maybe it is. I found a much nicer way to wait on the prefixer
process, if you can live with the "flock" dependency:
prefix_with_date()
{
local somelock=$(tty)
$@ > >(flock $somelock -c 'while read; do printf "%s: %s\n" "$(date)"
"$REPLY"; done ')
2>/dev/null flock $somelock :
}
prefix_with_date seq 10
Alternatives to flock might do; you got the idea.
