I got the same conclusion. Nevertheless, in my case with properly
chosen batch size I got results about twice as fast (~9-10 vs ~18-20 
minutes for
full rebuild) and with 1/3 of memory (~0.5Gb  vs 1.5+ Gb) which was needed
with one-step compilation.

Well, I agree that this is not safe in all cases but it does what it 
should do,
at least in my case. Perhaps it is too early to submit it for public use 

Thanks a lot for valuable discussion.
