What change would like to see?

Some method for doing non-blocking (buffered) serial write.

Is there some major complication with this, or is it just not a top priority 
right now? I was surprised to find the print/write methods block since the read 
method clearly doesn't and there's no mention of blocking in the documentation.

See: 
http://code.google.com/p/rogue-code/source/browse/#svn/Arduino/cores/arduino-ube
rcore/trunk/cores/arduino-ubercore for a possible implementation.

I've pulled that implementation into github (dbarnett/Arduino, issue262 
branch). I had to also edit Stream.h to fix the return type of 
Stream::available (from int to uint8_t).

Another possible implementation here: ftp://wookey.org.uk/arduino.  And in the 
Teensy code.  And see Siggi's library: http://siggiorn.com/?p=470.  Also in 
Wiring.

Can interrupt-driven TX also be added to the SAM core for Due?
