This should decrease the number of allocations before main is entered significantly, but complicates the code somewhat in return. Assuming I used `massif` right, doing just `SelfTest --list-tests` went from 929 allocations at "Remove gcc-4.9 from the travis builds" (2 commits up), to 614 allocations with this commit.
