This is about 3.3.rc2.

[Errno socket error] (8, 'nodename nor servname provided, or not known')
SOLUTION: This was caused by the networking being down during this
test. These tests should be marked # optional, since doctesting sage
*must* not require an external network connection. This is now

A mysterious error (perphaps a memory error?) occurred, which may have
crashed doctest.

IIRC this goes away if I try to build it directly without using ssh
and nohup. I upgraded Mandriva last time we saw this and that did not
fix it. Adding a warning to the README.txt under "known problems"
would be a good idea, if we can't fix this.
---
IMHO, the sooner we call an absolute 100% feature freeze on this
release and going into 100% "stabilize and release" the better.
