Tkinter/Pmw/Python 1.6a#: xsync?

[Rob W. W. Hooft]

I upgraded too many things at the same time: Computer, OS revision,
Desktop environment, and Python version....

For the python software that I make for my work, I also create a
package including the python interpreter and all extensions required
by my python code.

Since I upgraded to Python-in-CVS (from 1.5.2b1), Pmw0.8.3 (from 0.8)
and started running on RedHat Linux 6.2 in Gnome, I have the
impression that there are sometimes a bunch of X commands that stick
in the pipeline: the buildup of the GUI stalls every time for about 1
second just when the application starts a calculation or becomes
idle waiting for input. Dialog windows do pop up immediately, but
they stay blank for a while.

 - Is there anyone that has seen a similar effect? 
 - Is there a way I can avoid this?

Regards,

Rob Hooft
