Thanks greatly.  I don't mean to disallow -j in the long term, but I do need 
installworld to work in the short term. :-)  I guess I'll just reiterate, for 
the sake of rhetorical noise, that the problem appears to be the very concept 
of the info directory file, which is the one bit of the info install that 
can't be parallelized.  If we can find a way to generate that directory in a 
single step, as with man page indexing, then that should fix the problem.

Thanks again,
