High CPU while connected to serial (TinyG)

[perfectphase]

Not a high priority as it works, but when I connect to the TinyG, the CPU pops up to 25% on a quad core, 50% on a dual core, even while the system is idle.
Disconnecting drops the CPU down normal levels.
It also seems if the system is left idle for a minute then disconnected/reconnected the CPU will not drop and when reconnected it will double (50% on Quad, 100% on dual)

I noticed that as well while using it on the actual machine.
Search for improvements is planned for next release.
