I can't see how a screen saver would work that way!
                  ^^^^^^^^^^^^ 

One suggestion for the speed time:
After I tried Borland C++, I added the help system which is a TSR
(I can't use the integrated environment).  Having the TSR installed,
the compilation speed was the half!  One suggested that the TSR was
taking memory and this made any memory-consommer program slower (since
the program has to swap on disk when memory is full).  The memory may
be a major point if you save a graphics screen with some high definition card.

BUT, I was and still am a Zortech user.  And I did not notice the
compiler slowdown in having the Zortech _old_ help system installed
(I don't use the ZTC3.00r4 help which is from another dealer anyway and
is bugged : maybe like the Windowsmaker, the licencer will sale you 
the not bugged version :-(  ).

To summarize, depending on how you implement it, you may have a different
effect on speed.  One reason is the duration of service (you could use
an Assembler program to minimize time slice while waiting for screen
to be saved).  Another is the memory you are using.  And there maybe some
other reason (one nasty : if your program writes to some place in memory
and this modify the DOS or the foreground program; but lets presume this is
not the case).

One last comment : Zortech has a TSR package included with the compiler.
(It will allow _one_ entry by a special key combination and time slicing).
Other commercial or shareware packages may exist.
