I've pushed a number of patches to restore this functionality to:

http://git.samba.org/?p=abartlet/samba.git/.git;a=shortlog;h=refs/heads/lpcfg-for-tdb-mmap-control

(currently the top 5 patches)

Please let me know what you think, and any suggestions you have.  I
didn't make the loadparm optional in the end - it was mostly pretty
painless to add it to all the required places.  I'm running a 'make
test' on it here, but it looks good so far.

I'll add this as soon as I get the information from rusty about how to
do this.

Thanks,
