Comment(by SimonKing):
Also, the first patch doesn't apply to sage-4.7.rc2. So, I'll take care of
that as well.
Concerning idleness: It seems that there is a certain kernel patch for
Ubuntu that improves the pexpect performance. Namely, the problem with
some OS like Ubuntu is that the latency of pseudo-tty is to much (if I
understood correctly). After our sysadmin applied that patch, the problem
vanished.
So, the main problem with pexpect on some platforms is not a Sage problem.
That said, reducing the traffic in the pexpect interface is a good idea
anyway...
