Due to the death of the machine I was doing all my flightgear work on
I'm currently trying to set up another machine so I can still build
packages, but I've run into a bit of a problem. While my old packages
work ok on this machine (it's not gonna win any awards for framerates,
but it proves it works) the current cvs code segfaults on startup like this:
Program received signal SIGSEGV, Segmentation fault.

I'm guessing it's a problem with the GL capabilities of this machine,
and that we're now stressing th GL stuff more than we were before, but a
segfault isn't a particularly graceful exit, so I thought I'd better let
people know - maybe it's something we need to trap. Googling for
_glthread_SetTSD throws up lots of problems and very few solutions.
