read successfully reads the data, but then it's discarded by bash
----
It's discarded by bash because the read doesn't read 10
characters within the time limit. If you use -N 5, you get
your output. "-t" says it will timeout and return failure if a
specified number of characters is not read within timeout period.
If timeout is exceeded, then return status is > 128:
bash -c '( printf 12345; sleep 2 ) | ( read -t 1 -N 10 v; echo "s=$?,
<$v>" )'
s=142, <>
(status is > 128)
