[Ovmsdev] Memory leak

[Michael Balzer]

There seems to be a memory leak, after running the module over the past hours in my car, ssh couldn't allocate 4K for a new session and I had this status:

Nothing special to see. +14k on the events task vs. a fresh boot, but nothing that can explain the loss of more than 40k.

Odd, I'll watch this.
