+           "input module is broken after counting chunks");
+    assert(isReduced(Test.getProgram(), Test, CurrentFilepath) &&
+           "input module no longer interesting after counting chunks");

> Hi! I've hit this assertion failure because I'm using llvm-reduce to reduce a compile-time hog, so the interestingness test ("does it take longer than 1 second to compile") is not 100% consistent. Of course it seems to me like llvm-reduce ought to support this use case. Any thoughts?
In any case I think this should be a proper diagnostic, not an assert, like the "Input isn't interesting!" error.
