[Pythonmac-SIG] Re: MacPython 2.2.2 final candidate

[Alexandre Parenteau]

Hi Chris,

I have the same problem on OSX SMP, so here is what I do (gusiconfig.cpp) :

static void
PyMac_GUSISpin(bool wait)
{
    static Boolean    inForeground = true;
//    int        maxsleep = 6;    /* 6 ticks is "normal" sleeptime */
    int        maxsleep = 1;    /* 6 is to slooooow on OSX SMP */

    if (PyMac_ConsoleIsDead) return;

    if ( !wait )
        maxsleep = 0;

    PyMac_DoYield(maxsleep, 0); /* XXXX or is it safe to call python here?
*/
}

I changed maxsleep to 1 and it works much better for me. I've been running
this for 1 year or so.

I think the fundamental problem is GUSI yielding too much on OSX.
