[luatex] updates to various lua* packages breaks..something.

[Evan Cooch]

First time posting to this list. Apologies if posts 'like this' should 
go somewhere (or to someone) else.

After most recent (23 Apr) updates (I'm using MikTeX 2.9) to various 
things things related to lualatex (including base), I noticed that 
compilation of anything takes twice as long as it did (say) 10 minutes 
ago (i.e., before I applied the updates). Didn't take long to see why. 
Basically, now, every time I try to compile something, it re-runs 
luaotfload.

luaotfload | Updating the font names database:
luaotfload | Scanning TEXMF and OS fonts..

Every time! - it should only have to do this once, but since the 
updates, it tries to do this every time I compile the same file, which 
is where the added time to compile comes from.

Compilation itself does seem to progress 'correctly', but something that 
takes twice as long (because of what appears to be a bug causing 
luaotfload to run every time a file is compiled, is not an 'update'.

Wonder if its related to the following. If I bring up an admin cmd 
console, and run

mkluatexfontdb -f -vvv

I get an error:

mklualatexdb: Windows API Error 5: Access is denied
mklualatexdb: Data: C://Documents and settings

When I run this on my other machines - which I have not 'updated' - 
mkluatexfontdb runs fine.

Suggestions? Clearly something has been 'broken' during the update - at 
least on Windows machines running MikTeX 2.9.

Thanks in advance.
