/* attach/detach works to some extent under BSD and HPUX.  So long
   as the process you're attaching to isn't blocked waiting on io,
   blocked waiting on a signal, or in a system call things work 
   fine.  (The problems in those cases are related to the fact that
   the kernel can't provide complete register information for the
   target process...  Which really pisses off GDB.)  */
