[PD] GUI overload

[Miller Puckette]

This is just a guess... in s_inter.c, try replacing:

int sys_pollgui(void)
{
    return (sys_domicrosleep(0, 1) || sys_poll_togui());
}

with:

int sys_pollgui(void)
{
    return (sys_domicrosleep(0, 1) + sys_poll_togui());
}

It's possible that sys_domicrosleep(0 - which polls for input from GUI and
other FDs - isn't ever returning "idle" (zero) so that sys_poll_togui() never
gets called.

I've also seen a patch's GUI stop updating, but rather than bewail the fact 
that my GUI was dead, my immediate reactions was to be astonished that the 
sound was still working :)

I am wondering if there is a specific limit to GUI objects that could be changed. I think Pd is making some kind of decision that "there's too much of this stuff - I'm gonna prioritize the audio and not worry about it" and I'd like to know how or if it is possible to control this process from within Pd, or by setting flags on the command line.

Example patch enclosed to give you an idea. The really GUI-intensive objects are the trackers, especially quadtracker (which I think has pushed the GUI of Pd patches about as far as I can go now).
