hi there, when doing buildkernel one notices that the gcc or clang instances are spawned and closed so fast that top isn't fast enough to show them and the "last pid" field increases quite fast. obviously this produces quite a lot of syscall overhead. wouldn't it be possible to somehow spawn N gcc or clang instances (make -jN buildkernel) and then pipe the src to one of those N instances? just like with something like multics N processes were started and then people used the job control language to load binaries into those processes. cheers. alex
