be aware that if the binary is renamed (rpm upgrade) the "exe" will not 
be exactly "/usr/bin/gpg-agent"

# l /proc/505/exe
lrwxrwxrwx 1 glen glen 0 Jun  6 20:17 /proc/505/exe -> /usr/bin/gpg-agent*

# cp -a /usr/bin/gpg-agent /usr/bin/gpg-agent.save

# rm /usr/bin/gpg-agent
rm: remove regular file '/usr/bin/gpg-agent'? y

# l /proc/505/exe
lrwxrwxrwx 1 glen glen 0 Jun  6 20:17 /proc/505/exe ->
