> When a file is mapped, the view (size) of the map must fit in RAM.
i'm sure this is not right. i created a small ubuntu guest vm with
512MB ram and here's a python program that succeeds.
import mmap,os
SIZE=600*1024*1024
f=os.tmpfile()
print dir(f)
f.truncate(SIZE)
mm=mmap.mmap(f.fileno(),SIZE)
mm.seek(0)
mm.write("abc")
mm.seek(SIZE-5)
mm.write("012")
