We may be using the wrong BDB interface here. We use DB_ENV->set_alloc()
which only affects some of BDB's mallocs. I believe this is only for the case
where BDB returns malloc'd DBT content to the app. There is another
interface, db_env_set_func_malloc() which replaces BDB's use of malloc
globally, i.e., for its own internal mallocs as well as for anything it hands
back to the app. Is there any down side to using ber_memalloc for everything?
Also looking over the BDB doc makes me wonder if we should be using
db_env_set_func_yield or db_env_set_func_sleep as well. Thoughts?
