Hi folks, We're seeing a problem when disconnecting USB headsets in PulseAudio. Steps to reproduce are basically: start PulseAudio, plug in USB device, wait for it to suspend (pcm is closed but mixer is not), disconnect. Fairly often, this results in PA getting killed because the polling thread is realtime and exceeds its rlimit. The problem is not limited to
Missed one detail -- I've only seen this happen on the alsa-source thread, not on alsa-sink, but I've only tested with one device which has playback as well as capture.

Cannot reproduced this issue on ubuntu 11.04 Live CD with Logictech WebCam mic
PA server still keep running and Gnome Sound Preference automatically change the selected "input device" from USB microphone to on-board sound card when usb webcam is unplugged
Actully Gnome Sound Preference is lying about "no application is using the sound card" since it open the "monitor" at 25Hz (peak-detect" for displaying the vumeter of the microphone
