It seems very doable, since _popen/_pclose in Windows console apps
works in a fairly standard way. Adding an explicit pclose method
would be easy, although getting sensible errors (i.e. if called on a
file object not returned by popen) might take some work.
For Windows GUI apps, then one has to use something like lua-ex since
the C runtime version only works for the console subsystem. But this
is not Lua's problem ;)
