sabotage?

[sab123]

I've found an interesting code line in Xorg 7.2. It screws up the handling of EAGAIN/EWOULDBLOCK, and it's enabled only for SVR4 on i386 but not Solaris. Looked like someone has left a piece of debugging code in but the more I think about it the more it looks like an anti-SCO sabotage. I mean, what would be any good reson to put this code in? And who else is SVR4 on i386 and not Solaris?
