    * libraries have completed loading) and register it as a resident 
    * executable associated with the program binary's vnode, which is also
    * locked into memory.  Future execs of the vnode will start with a copy
    * of the resident vmspace instead of running the binary from scratch,
    * avoiding both the kernel ELF loader *AND* all shared library mapping and
    * relocation code, and will call a different entry point (the stack pointer
    * is reset to the top of the stack) supplied when the vmspace was registered.
