[Opensim-dev] Error detection when storing an asset

[Jim Williams]

Exceptions have proved to be one of the worst ideas ever added to C++.
 It's incredibly expensive code all around, from uwninding the stack to
handling the exception.

Actually, all code ought to be exceptionless by design, but most people
never bothered to learn group theory and once you add a single up-chuck
(throw) the whole system immediately becomes a mess.
