I'm not sure you're thinking about the problem in the right way. If they
compromise the system, aren't all of your agent sessions vulnerable?

You are much better off setting a reasonable inactivity timeout for your
session. Look at these settings in gpg-agent.conf:

default-cache-ttl N
max-cache-ttl N
default-cache-ttl-ssh N
max-cache-ttl-ssh N
