     This function is non-blocking and doesn't attempt to establish
     a socket - it merely prepares a connect to be performed later when

By default piggyback is enabled. Enabling piggyback is more efficient
and usually saves a network-round-trip for first time fetches of records.
However, a few Z39.50 targets doesn't support piggyback or they ignore
element set names. For those, piggyback should be disabled.
