Comment 37 for bug 147464

It occurred to me that the problem could be the network stack hanging. I mean X does depend on the network stack doesn't it? What happens if you're logged into a terminal instead? Would it still lock you out? What about processes in the background? A way to find out might be to run a program that writes to a file the time, at every, say, 5-second interval, for example:

#!/usr/bin/perl
while (1)
{
open(FILE,"$ENV{HOME}/test");
print FILE time();
close(FILE);
sleep(5);
}

And running that in the background.
