Yea, but I would have to malloc memory for each OVsearch call,
which I can not free until OVclosesearch is called, because
ovdb has no way of knowing when PushIOv gets called.

I don't want the nnrpds loading OV records for an entire group
into their private memory spaces.  It's just wasteful.

If you have a better idea for how I can deal with this problem,
please suggest it.
