I've been working on the problem of what should be non-blocking
serial I/O in GDB blocking, preventing GDB from receiving signals
when it should.  The culprit is the fhandler_serial class which
currently always blocks in reads/writes.

It looks like the solution has already been implemented in tty.cc (see
fhandler_tty_slave::read).  Where should this code actually be?  Could
we just make it more generic and then move it to fhandler_base?
