I'm wanted to trace down why some of my "compile-file" w/ no optimization was tasking time. I was able to turn compile-file under statprof for one of the moderate sized .scm files, which has about 45,000 lines of code. It was interesting that the major execution time consumer was reap-pipes. I'm curious where that fits in. Does anyone know how compile-file could be banging on reap-pipes so much? Below is the top output from statprof. The results are for a run using guile 3.0.2 on Ubunu 18.04/x86_64.
