[with workaround, needs proper patch] sage -t cubegroup.py & stops instead of running in background

[wjp]

When running sage -t cubegroup.py & (to run it in the background), the process is stopped.

This is caused by pexpect.sendeof() (called from rubik.py) calling termios.tcsetattr() on stdin which causes the process to be stopped with a SIGTTOU (=write to tty from a background process).

The pexpect.sendeof() function has been entirely changed in the current version of pexpect, and using that new sendeof() fixes this problem. So, updating to a newer pexpect (ticket #502) should fix this as well.

Attachment: trac-1683-partial.patch.gz

I merged trac-1683-partial.patch into Sage 2.9.2.rc1. But the ticket remains open for now since the workaround doesn't work on OSX.

Cheers,

Michael

I suggest that we can close this ticket now with the new doctest system.
