    libc - Fix bug in rcmdsh()
    
    * rcmdsh() (which really nothing should be using any more anyway) used
      a generic wait(NULL) to wait for a child to exit, but this can wind
      up waiting for the wrong pid in a multi-threaded or multi-fork environment.
    
    * Solved by waiting on the specific pid instead.
