> MDA has a known problem with overly large recursion cutoffs. I'd be interested to know whether passing -memdep-block-number-limit=100 would improve compile-time for your case.

Turns out that tweaking the memdep limits did help in my case.

So I guess I'm happy dropping this patch.  Though I *do* feel like there's still something here.
