Yes as @gergo- says, our inlining policy isn't well tuned for the Xcomp case so it can produce large graphs which hurts compile time.  We've retuned a little bit which helped many test.  We want to tune it further without nerfing it but that won't happen until all the real bugs are addressed.  We could revert these timeout changes if we make a good dent in the compile time.
