Why are the exec* functions deprecated in std.process?

That's really weird.  I've tried and failed to reproduce it with 
this minimal test program on my Linux box:

     int main(string[] args)
     {
         import std.process;
         spawnShell(args[1]);
         return 0;
     }

This worked fine with a variety of app names passed in args[1].

Are you able to provide a bit more context?  Such as:

  - Which platform are you on?
  - What happens before spawnShell()?
  - Which program is spawned?
