Looks like X Windows have some race condition or maybe it's in the kernel?
I've been running spamassassin learning which loaded the system. Then I
started X Windows System with "startx". During normal startup, a screen of
garbage flashes and is replaced with black screen and then with X background.
But this time, the garbage stayed. The learning was still running as I could
see by disk activity. I let it overnight and in the morning, there was still
garbage.
I know Linux has a problem like this - the console switching there is designed
in a flawed way, the simple signal mechanism contains a race condition, which
triggers typically during overloaded system. But that OpenBSD would have a
similar problem? Or is it a bug of the X Window System?
