Summary: comport hangs Pd and eats 100% CPU when port disconnected

Initial Comment:
Steps to reproduce:

1) Connect a serial over USB device, such as an Arduino
2) Create a [comport] and send it the appropriate "open" message to connect to the device:

[open N(
 |
[comport]

3) When the connection is established, unplug the USB device.

Pd will start eating 100% CPU and will hang. You won't even be able to close it, you have to kill the process.

This happens systematically here.

Pd Extended 0.42.5, Ununtu 10.04

I know you're not supposed to unplug a com port without closing, but Pd shouldn't hang.
