I do think that mergeing them would be a good idea and I can look into that, though at least locally that step takes less than a second.. I wonder if you might strace (or whatever is appropriate) that kdb5_util and see what's taking so long. I seriously doubt it's the actual kdb5_util code and strongly suspect it's some kernel call.
