ABI as FreeBSD's poll(2) is ABI compatible. The ibcs2_poll() function attempted to implement poll(2) using a wrapper around select(2). Besides being somewhat ugly, it also had at least one bug in that instead of allocating complete fdset's on the stack via the stackgap it just allocated pointers to fdsets.
