We do a lot of input validation in debug mode, so it's very valuable for
users to be able to choose between debug and optimized.  Our debug and
optimized builds are now binary-compatible (if other options match) so
you can build your application with optimized and then LD_PRELOAD the
debug libpetsc.so to get those checks.  It would be nice to have a
systematic (or at least recommended) place to put that debug library.
