[elephant-devel] Berkeley DB 4.4.20 Patch

[Ian Eslick]

Way to go!  Did you test against the current HEAD or the 0.6.0 release
branch?  All tests passed on 0.6.0 so if you are working from that
release you should be worried, but it's possible that not all tests pass
the current HEAD.  Also, did they pass before and after your fix?

In any event, I presume this change to the lisp code will not be
backward compatible to work with the 4.3 libraries? 

I'll see about rolling this change into HEAD tomorrow.  HEAD is slowly
moving towards an 0.6.1 release One of the nice advantages of 4.4 over
4.3 is that the system can compact btree storage without having to do a
dump and reload.

There are a couple of other small projects to tackle for 0.6.1 if you'd
like to get more familiar with the system!  I've been making some
strides towards better thread safety this week.  I hope to check in
those changes shortly.

Cheers,
Ian
