  /* sqUnixSecurity.c -- directory operations for Unix
   * 
   * Note: According to Ian Piumarta, the Unix VM is inherently insecure since
   *       pluggable primitives can access all of libc! It would need 
   *       some linker magic to hide these from dlsym(). 
!  *
   *       A workaround would be to disallow lookups via dlsym() when
   *       fileaccess is disallowed - internal plugins should still work ...
