1.0rc1 branche telnet to x.x.x.x 80 locks-up arduino

Using arduino 1.0 with 1.0rc1 branche webduino.

Telnet to webduino and type any character the arduino lock's up. Connecting to webduino via a browser works fine.
Telnet to previous versions of webduino is working fine.

Sorry about the closing and reopening. I thought I'd had it, but a final test before the push and I had the Arduino locked again :(
