Spawn Pipes

["J.D. Smith" <jdsmith(at)astro.cornell.edu>]

Any other unix 5.3 users out there have trouble reading from file units spawned
as pipes to a command?  Try this procedure:

pro simp
   cmd='ls'
   spawn,unit=un,cmd
   line=''
   while 1 do begin
      readf,un,line
      print,'GOT: ',line
   endwhile 
end

For me, almost every run results in an IDL segfault, though occassionally it
will work.
