I don't have anything significant to contribute to a revised interface
right now, but I just wanted to say that I think it is strange that an
import statement starts doing things like launching threads. The
import should just make an interface available, and then the script
can use the interface to create a "pymol object" or whatever:

  import pymol

  pymolHandle = pymol.create(options like window size, parent window to create in)
  pymolHandle.cmd.show("sticks", someName)

The pymol.create() blocks until things are ready, so it is sort of the
same as calling pymol.finish_launching(), but it seems more natural to
this programmer. I don't expect import statements to do much. If I
import imaplib it doesn't create an interface to an IMAP server,
right? It just gives me the ability to do so.

It would be up to the application to maintain or pass around
pymolHandle to various modules/objects to get things done.

Perhaps an app could use pymol.create() to create another instance, a
second rendering window? Shared model underneath? Hmmm. . .

When I delete pymolHandle or it goes out of scope, the thread should
shut down and other resources should be released. It should NOT kill
my application as it currently does when I call cmd.quit(). It's just
a thread, it shouldn't be making decisions for my application.
