  Changed paths:
    M src/lib-program-client/program-client.c

  Log Message:
  -----------
  lib-program-client: Fixed program_client_run() that succeeds rapidly.

program_client_run_async() could have called the callback with result=0
before io_loop_run(). This happened with local client.

Fixes in test-program-client-local:
Panic: BUG: No IOs or timeouts set. Not waiting for infinity.

  lib-program-client: Fixed potential panic in test-program-client-local

If the run finished before io_loop_run(), it would panic with:
Panic: BUG: No IOs or timeouts set. Not waiting for infinity.
