hi pavel,

thanks! this is a nasty one to fix, even if it may look like a simple problem. 
it
will probably have to wait until I work on type inference again. well, I know 
how to
fix it, but not without breaking some other things..

same problem here:

http://hbfs.wordpress.com/2009/11/10/is-python-slow/#comment-553

note that this is an easy workaround in this case, just help the TI a bit:

if False:
    solve(1, 1, [1], [1], [1])

yay, apparently the problem was easy to fix after the TI modifications for 0.2. 
both
examples now work with shedskin SVN. thanks pavel and james for sending me 
these! I
added the quicksort example to the test set in unit.py.
