Subject: [PATCH] Set CLOEXEC flag for pipes in PulseAudio plugins

I have noticed that Alsa / PulseAudio are leaking a couple of pipes after a
fork/exec, and have traced the leak to the following two plugins:

libasound_module_ctl_pulse.so
libasound_module_pcm_pulse.so

This is with Fedora 15. I have attached a patch for the problem.
