Three cheers for the GIL!

For the record, since I was quoted at the beginning of this subthread, 
*I* don't think threads are easy.  But among all ways to handle 
concurrency, I just don't think they are so bad.  And unlike many 
alternatives, they are relatively easy to get started with, and you can 
do a lot of work in a threaded system without knowing anything about 
threads.  Of course, threads aren't the only way to accomplish that, 
just one of the easiest.
