mmap( fileno, length[, flags[, prot[, access]]])
(Unix version) Maps length bytes from the file specified by the file
descriptor fileno, and returns a mmap object. If length is 0, the maximum
length of the map will be the current size of the file when mmap() is
flags specifies the nature of the mapping. MAP_PRIVATE creates a private
copy-on-write mapping, so changes to the contents of the mmap object will
be private to this process, and MAP_SHARED creates a mapping that's shared
with all other processes mapping the same areas of the file. The default
value is MAP_SHARED.
Apparantly, this is wrong - the default is not MAP_SHARED, as I just found
out the hard way.
