Making termios.tcdrain() work with threads?

[Grant Edwards]

I've noticed that calling termios.tcdrain(fd) (under Unix)
blocks all threads instead of just the calling thread.  This is
making life a bit diffucult for me, so I'm going to take a
crack at making it work "right".  Before I try, is there any
particular reason why it should behave the way it does now?
