I’m not sure why this paper got called “Minimizing Memory Usage for Creating Application Subprocesses”,it should have been called “MT-safe vfork and posix_spawn“. When UNIX was developed,processes were single-threaded,and this had some strong influences on a few of its basic mechanisms. vfork() is one of those mechanisms. If you’ve ever been bit by a thread deadlock inside the some goofy runtime linker routines,or if you’re interested in UNIX guts like fork and exec,read Greg’s paper for more information.
