man vfork:
The vfork() function has the same effect as fork(), except that the 
behaviour is undefined if the process created by vfork() either modifies 
any data other than a variable of type pid_t used to store the return 
value from vfork(), or _*returns from the function in which vfork() was 
called*_, or calls any other function before successfully calling 
_exit() or one of the exec family of functions.
