Comment(by sitsofe):

 Some good news! It looks like gstreamer has adopted a patch to workaround
 this problem: http://cgit.freedesktop.org/gstreamer/gst-plugins-
 good/commit/?id=1e2c1467ae042a3c6bb1a6bc0c07aeff13ec5edb (via
 https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/644644 ). This
 means the problem is not showing up in a recent Fedora 15 alpha
 (gstreamer-plugins-good-0.10.27-3.fc15.i686)...

Comment(by sitsofe):

 Further testing on the 2Ghz laptop shows that nothing over speex-float-1
 will prevent pulseaudio from dying/being killed when gst-launch starts
 playing the sample. However, if the initial gst-launch can be repeatedly
 paused and restarted then it becomes possible to play the sound - so it is
 the initial spike in CPU usage that is causing the issue.

 Perf output was collected for as long as gst-launch was running (it stops
 early when pulseaudio crashes).
