I asked Jeff at the Cauldron, and he confirmed there is an issue with

Right.  Though it's far from certain the ext-dce problem is the cause of 
the compile-time slowdown or not.  In fact, it looks like Aurelien may 
have concluded its not ext-dce, but more likely location views.

There's been some talk of disabling some of the debugging bits that 
don't have consumers (statement frontiers, maybe others).
