No, it normally wouldn't consume anything.
Firstly, /dev/shm is a tmpfs, i.e. a RAM file system, so no Flash
space should be allocated for it ever (unless you swap to Flash).
Now, it usually doesn't even consume much RAM, because as I said
multiple times already: the size of this shm file does NOT reflect the
actual use of RAM, it reflect the use of address space. Use "du" to
figure out the use RAM.
The file size reflects the amount of reserved address space.
The disk usage ("du") reflect the amount of used RAM.
