It looks like the mock subprocess is dying before kojid can wait on it. 
Normally mock should never exit that fast, though we should probably 
handle that error a little more informatively.

Try running mock manually on your build system to see if you can 
replicate the error that way. You might also try running kojid in the 
foreground (--fg option) in order to see the output from mock.
