Investigate if Access can utilize Phaser like done for BufferLease in teragrep/rlp_03#61

Adding Lease phaser as a sub phaser to Access phaser terminates the Access phaser if a lease is opened and then closed, and it can't be used in getting new leases after one time. This does not work as the Access object is shared for multiple leases.
