Relates to work done with releaseConnectionAfterResponse

Results from some testing
Under 2.6 we do have some leftover connections, compare:
Pre Test (18 sockets with LSOF)

	"totalAvailable" : 9,
	"totalCreated" : 10,
	"numDBClientConnection" : 10,
	"numAScopedConnection" : 1,
	"ok" : 1

Post test (86 sockets under LSOF)

	"totalAvailable" : 15,
	"totalCreated" : 25,
	"numDBClientConnection" : 84,
	"numAScopedConnection" : 10,
	"ok" : 1

However, under load there are 186 open sockets open during the test.

This shows that connections are being closed by RCAR, but there may also be some leftovers. We need to investigate this.
