Ah, so it is already possible to configure these sizes differently.
I'm not sure, perhaps Roger

These systems can set the values using TMPFS_SIZE, SHM_SIZE, RUN_SIZE
and LOCK_SIZE, if they are unhappy with the default values.

Perhaps. /dev/shm/ is well defined and out of scope for how dosemu
and user-mode-linux uses it,
