Interesting that it seems likely to occur on fast machines running XP SP2, 
but not not on a PIII.  I was also able to reproduce the same type of 
glitches changing windows on my XP SP2 Pentium M 1GB RAM laptop.

So, XP users, let's try this - run chuck with the --level10 flag, which 
should internally boost chuck's priority:

     > chuck --level10 foo.ck ...

For me this got rid of the glitches.  If this works in genereal, we can 
make this a default.  Also feel free to try other values.

Let us know!
