We can use virtual destructor only with memory release. We use close()
for the same reason on which have been entered ib_util_malloc. In
plugin code implementation like
::close()
{
.....
delete this;
}

Its good idea. For realization we must have flat array of DSC*, and we
haven't it in firebird and plugin engine. All value of ResultSet
stored separately, we extart it from JVM and convert on the single.
