[pygame] Thread issue in my graphics API (pygame)



Link to the mentioned file: http://dc.ubuntu-us.org/projects/gasp/

My system: ubuntu-dapper (2.6.1).  Line 325 is where the _event_handler is and I believe causes the issue.  I can recreate the bug quite easily by calling the 'begin_end()' method and letting it run until it breaks (2-7 seconds mostly).  I cannot even confirm that this will run on Windows or Mac OS X.

I am having a problem with using a thread in my program (attached).  I have an event handler which I have run in a separate thread, which redraws the screen (linux) and quits if the 'x' is pressed.  However, I seem to be running into a threading problem with this set-up.  When I attempt to close the graphics window, I will occasionally (about 20-30% of the time) recieve an error message:

    "Xlib: unexpected async reply (sequence 0x##)!" (where ## are two numbers)

I googled it and found that it's a threading issue, but not much more, such as WHAT is actually wrong or ways to avoid the error.  I'm looking for anyone out there that can help me solve this issue, your help would be much appreciated.
