Hi Stefan,

We used to have atexit(bf_exit) code for cleanup.  With the addition of
transactions last year, it was no longer necessary and was removed.

Since it seems to be needed again, I've resurrected the code and it's
now in cvs.

By the way, are any of your crashes reproducible, hence fixable?

Regards,

David
