The <code class="methodname">DbTxn::set_priority()</code> method sets the
priority for the transaction. The deadlock detector will reject
lock requests from lower priority transactions before those from
higher priority transactions.

By default, all transactions are created with a priority of 100.

The <code class="methodname">DbTxn::set_priority()</code> method may be
called at any time during the life of the transaction.
