Thanks. I think we must be looking at a XeTeX bug here, but I'm not yet 
sure exactly what is causing it. If I load the Sanskrit patterns with 
the plain-based XeTeX format, and try some of your text, it seems to 
hyphenate fine; but in XeLaTeX something breaks.

The problem occurs whether or not you include \language=\sanskrit in 
your document, which makes me think that the issue may be somehow 
related to loading the patterns (and corrupting something), not to the 
actual hyphenation process. The current file doesn't seem to fit the 
pattern of how other languages are loaded in LaTeX (the hyphenation 
files themselves don't do \newlanguage, for example; that must be 
handled elsewhere); maybe someone who knows more about LaTeX/Babel/etc 
can look at that stuff.

However, even if there are issues with the LaTeX language name/code 
setup, etc., that still doesn't really explain the bad output; I do 
think there's a XeTeX bug here, but I'm not going to be able to dig in 
to the code for a few days--deadlines are looming! :(
