4.0 leafify timings, this time on the same machine (sigh!) as the 4.1 numbers:
Execution times (seconds)
garbage collection: 4.56 ( 4%) usr 0.08 ( 1%) sys 4.66 ( 3%) wall
callgraph construction:

-ftime-report for the 4.1 + flatten compile:
Execution times (seconds)
garbage collection: 6.32 ( 4%) usr 0.07 ( 1%) sys 6.73 ( 4%) wall
0 kB ( 0%) ggc
callgraph construction: 0.42 ( 0%)

For 4.1, we have cut the runtime in half while less than double the compile
