21:26:57Bikedrmeister: do you remember the purpose of this commit? https://github.com/clasp-developers/clasp/commit/97f9f147a35d9b18d9581bcd7c816aa45aecd894
21:27:51BikeAs far as I understand, it delays process-run-function and stuff from returning until the thread is just about ready to call the lisp function
21:30:35Bikethe stuff in the critical section includes mps registration, allocating and initializing the thread local state, getting the dynamic variables set up
