The solution to all problems in Computer Science is already known:
"add another level of indirection". [Tcl and Perl version ..
double the quotes and escape characters .. :]
In this case:
a) the Desktop must keep track of its file descriptors F
b) it starts Helper which is passed F and closes them
c) Helper then starts Plugin with no open file descriptors:
--> Plugin doesn't need to close inherited file descriptors
If Desktop doesn't do that, Desktop is screwed.
