Re: [matplotlib-devel] Fwd: Re: [Matplotlib-users] show() blocks script execution for TkAgg from ip

FWIW, I responded to a thread on the IPython list where someone else
was asking why show() was blocking execution on Windows 7.  I think he
was really experiencing the tk show() problem from mpl.  So, I think
this is causing issues with other users (in my opinion).
