Well, I thought that we were doing all the necessary tricks to make sure that
'normal' wx scripts would work OK under -wthread, without needing any

In fact, I tried the example and it runs fine for me, regardless of how many
times I close/reopen it.

Note, however, that I had to modify the code a little:

import wx
app = wx.PySimpleApp()
win = wx.Frame(None,-1, title='Hello World!')

Note the extra -1 in the Frame() call.  With that change, I can close the 
window as many times as I want without any problems, and I tested this both 
under Fedora3/WX 2.4 and ubuntu/WX 2.6.
