PulseAudio shows up as memory hogger in top! Why?

https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/MemoryConsumption/

When starting up PulseAudio allocates a 64 MiB shared memory segment and then for each active client another 64 MiB segment is added. For the uninitiated this might look as if PA wastes substantial amounts of memory. ... You may control the size of the shared memory segment by changing the "shm-size-bytes" configuration option in "daemon.conf".
