The chattering problem seems to have been relieved by the latest changes, but when I try to run make world I am still crashing during the library install phase. The symptoms are a little different now: I get "panic: freeing busy page" from a process running "install" trying to exit (i.e. in the exit system call). The panic occurs when vm_map_remove() is called at line 148 of kern_exit.c. The page in question is marked "bmapped", and the attempt is made to free it from within vm_object_terminate(), so I have the feeling that the object reference counts are still not quite right yet. - Gene
