Comment(by drkirkby):

 Replying to [comment:2 rlm]:
 > This has nothing to do with the file `BSD.py`. It is a bug in the
 doctesting code, which is triggered (as William tells me) by lag times on
 file systems and the like. It starts testing before the doctesting file is
 created.

 I run that test more than once and it failed more than once.

 Note although the machine is rather old (900 MHz CPUs), the disks are
 local, with a 2 Gbit/s fibre channel interface and 15,000 rpm, so the disk
 performance is probably better than most modern PCs. If the disks were on
 a NFS file system, I could perhaps understand that, but it seems unlikely
 with local disks like this.

 I managed to mess up my build (started a 64-bit build in the same
 directory as the 32-bit one!), so are rebuilding now. I'll try again once
 complete.
