The 'exit' command exits the subshell you just created.

Hi,
I found out a very unusual feature of bash which makes it to act really
unexpected. I understand that pipelines are executed in a separate subshell,
but I really think 'exit' command should be absolute. Consider a trivial code:
#!/bin/bash
echo Start
ps -ef | while read proc
do
echo $proc

I'm not convinced of the need.
