+terminated successfully. Also, while waiting for the process to
+terminate, wxExecute will call \helpref{wxYield}{wxyield}. The caller
+should ensure that this can cause no recursion, in the simples case by

For asynchronous execution, however, the return value is the process id and
zero value indicates that the command could not be executed.
