Hello. The wiki page http://pulseaudio.org/wiki/MemoryConsumption reassures us that PulseAudio will not eat our RAM: PulseAudio allocates 64 MiB of address space, but the big part of that address space is not assigned to RAM, therefore all is o'kay. However, if "lock-memory = yes" in "/etc/pulse/daemon.conf", than PulseAudio does eat RAM. Because no real-time process may have its address space unassigned (or assigned to a swap, BTW). If you agree, I will add real-time considerations to the wiki page.
