Ok.  It does let me eventually get to the terminal to kill Pd, but just
barely :)  Would it be a better solution (or even possible) to force Pd
to turn off DSP, or maybe lower its priority by a lot?  Pd didn't
respond when I tried to turn off DSP (using ctl-.), so I had to kill it
and lost the changes I'd made to my patch.

This happens to me on an Athlon XP 1800.  But so far only with largeish
patches that use several externs and plugins, so maybe one of them is
the cause.

Thanks,
