Actually, it is available, but not through any nice pramatic interface.

If you set the environment variable GLKONA_DLIST_USAGE before
running your program, you will see output from the
display list manager every time a dlist is pulled from the host (IDMA)
to be added to the dlist cache.
The LDMA numbers (LDMA: %in use XX XX of XXMBytes)
show the MBytes taken and the % allocated actually in use.
The other XX numbers are for internal usage.
This is also a helpful debugging facility: if the output doesn't
eventually stop, you must be referencing dlists that are not in the cache
and having to come from the host.
