What about `shutil.copy()`?

Without processing the data read? shutil.copy2 or similar
Else, a lot of applications can follow the pattern read-process-write: read
a logical block, process, write the output; where "logical block" depends on
the application: a record, a frame, a chunk...

How huge? I regularly process 100-megabyte MPEG files in Python, both by
reading the whole thing in as a string, and by using "mmap" to map the file
into memory.
