You can make a file with a hole by seeking past it and never writing to that bit, but is there any way to punch a hole in a file after the fact? (I mean other with lseek and write. Having a sparse file as the result....)
What are the downsides of holes? (How big do they have to be to actually save space, is there a performance penalty to having a file with 1000 4k holes in it, etc...)
