gpg-agent directories in /tmp

Chris,

 : I've got a bunch of directories in /tmp that are like this:
 :
 : and so on, about 25 all together. What is their purpose and can 
 : they be safely removed? What is the purpose of the S.gpg-agent 
 : socket file that is 0 bytes?

Look for other UNIX sockets on your system.  They should also have a 
filesize of 0 bytes [0].  There are probably better scripts than the 
attached for cleaning up the temporary socket files, but this will 
do the trick.  When you fire up gpg-agent, it creates a new mode 
0700 directory in which to store the socket itself.

When gpg-agent is allowed to exit gracefully, it should clean up its 
sockets (see atexit handler called cleanup in gpg-agent.c).

Best,

- -Martin
