In my case (I'm the OP), the problem indeed turned out to be with my 
font files--I had two versions of the CharisSIL font files, with 
slightly different names.  Apparently it (Cygwin, and therefore XeLaTeX) 
was picking up the older ones, which were known to have issues with 
small caps.  I imagine this problem could occur in other OSs, since the 
font file naming issue would affect those systems too.

I haven't tried this on my Windows/Cygwin machine yet (I'm on another
