I feel odd about this, shouldn't we create a new instance instead?

[bpastene, 2016/07/23 01:17:39]

Yeah; I tried, but ran into a couple of problems:
- Who does the creating? And how would it know to create a USBHandle vs
TCPHandle?
- For a single device, there are multiple references to that device's handle (in
HighDevice, AdbCommandsSafe, AdbCommands, AdbConnectionManager, etc.) I didn't
feel like hunting down each one. 

Better to let the handle itself do all the changes it needs to, I think. But I'm
willing to go with another approach, if you feel otherwise.

No, that's fine. Not worth reengineering.
