Hmmm...

I wonder if this change should wait until the xterm sets the ownership
on the pty (ie: maybe it should not happen at all).  Specifically, you
really don't want someone to be able to open the slave side before the
pty is allocated, and has a master -- maybe not even then, until the
program that grabbed the master provides the slave process itself?
