Sure no harm waiting not like its a resource hog but why wait indefinitely. The only reason for coding something like this would be to provide a shell environment for other programs.

If you want a timeout, you need to set things up with a timeout of some sort, then check the result and deal with what happens if you get a timeout. What are you going to do if there is a timeout? Exit, I suppose?

Just a suggestion and as the O/P is content with waiting so be it and of course it keeps things simple. Certainly the code gets complicated if the program needs to either exit after a certain time or supply a default value and continue instead of waiting indefinitely.
