final output lost when command exits quickly after reading from stdin

[Teppo Sulavuori]

Final output generated after read from stdin is lost by empty if command exits quickly after the read.

All output comes through fine if:
-there is a lot of output after the read
-command waits for a small time after the read (no matter if waiting before or after the final output though)
-command does not read from stdin

Example scripts attached.

Commands:
empty -f -i in -o out ./script.sh
cat <out
echo Test >in
