Memory Leak ?

[front-a-little]

I'm using websql Plugin version 0.0.9 in Cordova 5.0.0 and platform "windows".
For performance tracking I use Windows Power Tools attached to either the emulator or the device.

In a readTransaction, when the success callback is invoked, you can see the used memory going up but I expect the memory to go down again once I've processed the result data and don't hold any refernce to it anymore. However, this is not the case, memory adds up each time I execute a readTransaction.
The transaction has one simple select query and I've set the result to null for testing where I would pass it to the cosuming function. Does the plugin maintain any kind of internal cache ?
