It doesn't actually take a minute to get the connection, it's just a safe and reasonable timeout.

Why does it take a minute to get a connection?  With a connection pool, it should literally
be milliseconds....

	Under a heavy sustained load, the sqlmaps ThrottledPool seems to start to bind, the the vast
majority of them binding up and blocking waiting to build a new session, and stay blocked
long after the fact, even days after the request has been abandoned. Any help would be appreciated,
and I am attaching a thread dump.
	My code looks like:
	 private void executeSqlMapTemplate(SqlMapTemplate t) throws SQLException
	        final Connection c =
	                        1 * 60 * 1000l); // Waits a minute for a connection
	        if (c == null)
	            throw new IllegalStateException("Unable to retrieve JDBC Connection from db pool.");
	            SqlMapSession sess=this.sqlMapClient.openSession(c);
