backend('fltk') use large amount CPU resources on MinGW

[Tatsuro MATSUOKA]

Hello

When I execute

>>backend('fltk')

the amount 55-80 % CPU resources are used on my old computer (Win XP Celeron-M 
1.2 GHz) on recent
development source.  The platform is Windows

The above happens even if no plot was carried out.

I cannot
Of course, for recent powerful computers this is not so serious.
However, considering of use of netbook, this might not be desirable.

Why only the backend('fltk') (without plots) command use large amount of the 
CPU resources?
Is this specific to the windows.

Octave 3.2.4 has an experimental version fltk backend.  In the case,

>>backend('fltk')

does not use so much CPU resources.

Anyway I will look into this using debug facilities of the octave.

If someone give me suggestions, it will be grateful.

Regards

Tatsuro
