If it is only used for the parent to signal the child to terminate?

Why should AST's be a problem?

The "call this function when task is done" approach is
a very common design today. DEC was ahead of time with
that.

And implementation wise then the AST's worked on VAX 700
series 45 years ago. Todays systems are extremely much
faster - maybe a factor 10000 faster.
