ENOMEM, based on my recollection of the strerror message; I'm not currently writing from the machine from which I produced this failure, and haven't reproduced it here. I had been running a version with a debug_logprintf() to complain about mapping failures; I believe I may check that code in, as it could be potentially useful information. Which is a bit odd, since I didn't get that the first time or two I ran it. I suspect there may have been a bit of kernel oddness or something. In any case, though, we should assume mmap() could fail. It's certainly possible for a file to be large enough that it cannot be mapped into memory. - -- Micah J.
