I hope I'm not (again) chiming in late here, but I hope we're 
building Quesa (or at least, making it possible to build quesa) with 
exception support turned off.  In at least some compilers, having 
exceptions on incurs a noticeable overhead even if you're not using 
them.

My experience also matches Dair's, i.e., that in C++ code, exceptions 
tend to cause more grief than good.

Best,
