"Isn't proper OTP" is often code-speak for "doesn't work well under
failure" or "the failure mode isn't handled". In other words, the system
works well until failure, and then it starts becoming fragile.

In 'eldap's case, opening a connection spawn_link/1's a worker process and
ties it to the current process. A more OTP-like approach would have been to
use 'proc_lib' to make the spawned process adhere to the OTP design
principles, but perhaps there isn't a need for it to do so. Tobbe is no
newcomer to Erlang and he generally knows what he is doing, so chances are
he had good reason to handle the problem as he does.
