I don't want to introduce a requirement that the regression tests need to 
be run on file systems which either support sparse files or have lots of 
space available. If someone wants to run tests on a FAT file system, I'd 
like that to be practical.

If there was an overwhelming benefit to some test needing a particular 
environment, that might be another matter. But it doesn't seem to me that 
an actual large file test offers much advantage over a surrogate, as long 
as the surrogate accurately reflects reality. We will see if that is the 
case.

Thanks,
