HOW TO: have multiple plot windows open at the same time?

Yes, this is the problem that Bill describes about needing a separate
GUI thread to allow both the plots and the shell to work
simultaneously. You need to try one of his solutions to get around the
issue - I highly recommend using ipython -pylab, which will take of
all this completely transparently for you.

Yes, this solves most of my problems, except that show() still does
not return until I close the charts.
