Thanks for the fix. I grabbed the changes from CVS and applied/tested  
them here.

Any idea about the hangs in t.lock3? (Should I just stick with bdb  
for now?)

When the tests hang it looks like all the processes have similar  
backtraces:

I do see this in the SQLite bug tracker. I don't know if it is relevant.
