If you want a non-blocking
version of ExecWait(), why not simply use Exec()?
Am I right that you want to create the process asynchronously and then wait for its termination at a later point?
In that case ExecShellWait() from my StdUtils plug-in may be possible way to go:
(It splits creating the process and waiting for its termination into two separate commands)
