cvs diff vlv.c

File:
  back-ldbm/vlv.c

Problem description:
There was another source of deadlock.
vlv_build_candidate_list creates db cursor in it.  The current code locks the
vlvSearchList, calls vlv_build_candidate_list, then unlock it after the
function returns.  Creating db cursor should not be inside of the vlvSearchList
lock.

Changes:
Before creating db cursor, unlock vlvSearchList.  It should be safe since there
is no chance to traverse the vlvSearchList.
