Make the master fd belonging to the pty pair non-blocking. Writes were blocking
if the console client disconnected before all the data had been written to the
pty, even though the select call had indicated that the fd was previously
writable. Reads have been observed exhibiting similar behaviour too.
Closes bug #380.
