Open PDF

IMHO, the fact that there is no way to wait for the application to
finish is major deficiency with os.startfile() -- and why I often
cannot use it instead of other techniques [such as the much more
involved but limited os.spawnv() function].

I don't if if this is just a limitation of the implementation in the
Python os module or one with the underlying OS (Windoze) -- I suspect
the latter.
