Probability of ld.so breakage is quite low, much lower than any of the
base libs, therefore it could be a resonable middle ground. IMO there
could be 2 options: middle-case applicable in the most cases (i.e. dynamic
executable linked against static libs) and fully dynamic executable for those
who want to overload standard functions. Of course there could be third ege
case (fully static binary) for those too paranoid...

Just my US$0.02.
