Patching select_backend() will affect 30-some files, so I'm not sure 
we'd want to change this in 2.2. On the other hand, a patch against CVS 
HEAD would probably port equally well to 2.3 and 2.2. Multiple-suffix 
support is not a priority for us though, it's preferred that you use one 
suffix per database. Overall I'm less inclined to patch this in 2.2.

As a hint, you need to add an (int *) argument to select_backend, and 
add an o_isuffix (or something) to the Operation structure in slap.h, 
and reference it consistently in back-bdb.
