Thanks Peter.  This got me started.  Apparently Mathematica doesn't have 
any way to open a file from simultaneous reading and writing, which I 
find strange (although given Mathematica's perspective on streams, I 
guess it is understandable), but I was able to re-implement RunThrough 
using ReadList:

RunThroughQuietly[cmd_String, expr_] := Module[{ret, s, filename},
   s = OpenWrite[];
   filename = s[[1]];
   ret = ReadList["!" <> cmd <> " < " <> filename];

I'm not sure why RunThrough doesn't take an option to not show the 
window (maybe nobody thought of that), but the above implementation 
seems to work well enough for what I'm trying to do.
