openssh-agent polling

[Alan Jenkins]

This may be a stupid question - but why does ssh-agent fork off a 
child and then exec the subcommand in the *parent* process?  It forces 
the agent in the child process to poll the parent, so it can exit when 
the parent finishes.  If the agent was the parent process, it could 
use wait() instead.  I'm sure there's some reason.

It'd be nice to take ssh-agent off the list of polling processes you 
get with powertop[1], however far down it is.

Please CC me in replies
