Probably tens of thousands of lines of code.

No, that's not quite right. The choice is "arbitrary" by default, which
means that the Ada run-time system can always pick the first one. It is
not (necessarily) random. If you select the Priority_Queuing policy,
then it's more deterministic: it always picks the first one (see
D.4(14)).
