awaitpid is the new API which will eventually replace dwaitpid.
It enables early registration of callback handlers.  Eventually
(once dwaitpid is gone) it'll be able to use fewer waitpid
calls.

The avoidance of waitpid(-1) in our earlier days was driven by
the belief that threads may eventually become relevant for Perl 5,

introduce optional threads via C, but they definitely won't be
spawning/reaping processes.

flattened multiple arguments more natrually.  The previous API
(allowing only a single argument, as influenced by
pthread_create(3)) was more tedious as it involved packing
