This was fixed a while back. Not sure if Hans released a beta after that. 
IIRC, in math-map.lua table.merge needs to be changed to table.merged (or 
vice versa?)

Sorry, I should have mentioned that I'm testing against texlive-2010
pretest.

This bug was fixed two weeks back, and as such is not fixed in TL.

@Taco: Does it deserve a hotfix in TL? It is just a change of two lines.

Already months ago texlive 2010 was frozen and therefore the context
on it is one of a few month ago. I get the impression that other tex 
macro packages keep updating but we keep frozen. After all, it's a 
snapshot and users can update any time. We could of course push a recent 
version but the luatex binary used on tl is not the latest and we don't 
want to enter testing new cache code in tl 2010 now.

So .. do no use the tl 2010 version as benchmark (esp not for things 
that evolve due to fixes in the engine, improved insight, more benchmark 
fonts, etc).

AFAIK, texlive 2010 freeze will start from tomorrow, so it was not frozen
before.

Sure, if you send me tested patch against TL10/pretest
(I don't run pretest any more, and I don't trust copying files
from the current beta).

Best wishes,
Taco

See attached patch, for the Gamma and Pi as well as the corrected 
definition of \mathgreekitalic.

(I tested with Cambria rather than xits, but that should not matter here).

Yes, but the TL binary freeze is much sooner (and for good reason). 
Freezing luatex effectively freezes ConTeXt MkIV. Bugfixes and new 
features must be added selectively to pretest, which makes testing much 
harder.
