Martin Panter added the comment:
Calling BufferedReader.read1(sys.maxsize) gives me a MemoryError. Making read1(-1) equivalent to read1(sys.maxsize) only makes sense where the return value already has a predetermined size, and only a limited buffer needs to be allocated.
Another interpretation is to return an arbitrary, modest buffer size. This is what I ended up doing with LZMAFile.read1() in Issue 23529: return no more than 8 KiB. It is not equivalent to sys.maxsize because more than 8 KiB is possible if you ask for it. HTTPResponse (for non-chunked responses) is similar, but uses a default of 16 KiB.
