For example, libevent has
{{{
void event_set_mem_functions(
void (malloc_fn)(size_t sz),
void (realloc_fn)(void ptr, size_t sz),
void (free_fn)(void *ptr));
}}}

tevent is unique - it is built on top of talloc, a memory allocation library with some interesting features such as constructor/destructor-like functions. So we can't change tevent.
