This doesn't sound right. 340 *MB* is just too much.

It might be useful to look at smem to get the USS:
$ smem -P '\bpipewire'
  PID User     Command                         Swap      USS      PSS      RSS 
 2450 zbyszek  /usr/bin/pipewire               2288    22592    23265    28700 
 2452 zbyszek  /usr/bin/pipewire-pulse         3412   241784   242097   246924 

So 241 MB of non-shared data seems like a lot.
It seems like pipewire-pulse starts with reasonable memory use,
but then grows quite a lot over time.
(This is still with 0.3.40. I'm upgrading now and I'll report if this changes
significantly.)
