Given that theirs has choked several times on some fairly common

the first or best place to look.

It may seem so in the rear-view mirror, but had you NOT done the 
low-level infrastructure, AND the 2+ year code-clean-up of what was 
adapted from Free (and other) BSD, nothing else would be working as well 
as it does.

That was time that pays back with long-running and ongoing dividends.
