 Pulse 0.9.7 on Arch Linux with kernel 2.6.23.1, with a hda-intel audio
 device.

 Here's the out from the server:

 {{{

 }}}

 Then in a different terminal I run for example "pasuspender sleep 5", and
 the server outputs this:

 {{{
 D: module-oss.c: trigger
 D: module-oss.c: trigger: 1
 D: module-oss.c: clearing playback buffer
 I: module-oss.c: Suspending...
 I: module-oss.c: Device suspended...
 I: module-oss.c: Trying resume...
 D: oss-util.c: capabilities: DUPLEX MMAP REALTIME TRIGGER
 }}}

 And then the server completely hangs and I have to kill -9 it.
