Hey cmpilato --

I know that you discovered this 'out of stack' error when you tried to
'svnadmin dump' revisions 0-1000 of our real repository today.

If the problem is indeed nothing more than
"oh-my-god-we-need-a-delta-combiner", then the good news is that I've
been able to run this process just fine on my FreeBSD system. (Maybe
FreeBSD has no stack-size limit, or a much higher one?)

Anyway, my box has been running the dump for 7 hours now, and it's up
to revision 750. I suspect it will finish the dump soon, so that
we'll at least have half the data we need for migration to a new
repository schema. (Interestingly, I've watched the RAM footprint
move up and down for hours, ranging from 25 to 75 megs, and generally
hovering around 50. Thank goodness for Sander's pool changes!)
