Awesome! :)

Next order of business:  Improving the exec* API.  The following is an 
excerpt from the documentation:

     int execv(in string pathname, in string[] argv);
     [...]
     Typically, the first element of argv is the command being executed,
     i.e. argv[0] == pathname.
     [...]
     Returns -1 on failure with no indication of the underlying error.

I find this extremely unsatisfying. First of all, there is really no 
need to repeat pathname in argv, and secondly, the functions could 
easily throw an exception with an informational error message based on 
errno.

I suggest deprecating these functions on POSIX too, and creating new, 
POSIX-only functions with equivalent functionality but an improved API.

Thoughts?  Is it worth it?
