FWIW, there's currenly only one patch (118833-36 and its counterpart 
118855-36 for i386) that makes pca stop patch installation as it 
requires an immediate reboot.

Right now, there are only two exit codes: 0 if pca completed 
successfully, and 1 if there was an error. In a wrapper script you might 
have to parse pca's screen output for more detail.

More useful exit codes are pretty high on pca's ToDo list, it's just 
that it will take some time until I go through the complete code and 
come up with a list of usable exit codes.
