*
* void lib(void) {

*
* This won't actually aspect fork() until pthread_create() is called,
* since we don't want normal non-threaded programs to have to acquire
* exclusive locks on every resource in the entire app just to fork().
*
* The vfork() function is *never* aspected. What happens instead is a
* global variable named `__vforked` is set to true in the child which
* causes lock functions to do nothing. So far, it works like a charm.
*

* @param parent is run by fork() after forking happens in parent process
* @param child is run by fork() after forking happens in childe process
* @return 0 on success, or errno on error
