Sorry Eric, but I can't reproduce this.  I tried it on XP and 2K8R2
with identical result.

That's what I get in bash:

  corinna AT cathi ~
  $ ls //home
  ls: cannot access //home: No such file or directory

  corinna AT cathi ~
  $ cd //home
  bash: cd: //home: No such file or directory

  corinna AT cathi ~
  $

And that's what I get in dash:

  $ ls //home
  ls: cannot access //home: No such file or directory
  $ cd //home
  cd: 2: can't cd to //home
  $ 

> $ dash -c 'CDPATH=/; cd home'
> //home

On my systems this result in:

  $ dash -c 'CDPATH=/; cd home'
  cd: 1: can't cd to home

I also tried a simple test application which removes the shell
magic from the picture:

  #include <stdio.h>

  int
  main (int argc, char **argv)
  {
    int ret = 0;
    if (argc > 1)
      ret = chdir (argv[1]);
    if (ret)
      perror ("chdir");
    return 0;
  }

  $ gcc -g -o chdir chdir.c
  $ ./chdir //home
  chdir: No such file or directory
  $

If you're able to cd to //home, then there must be some crucial
difference in your environment.  You should debug this, at least with
strace, so we can find out under what circumstances this occurs.
