IO specs fail after changing IO::BufferSize while they should not
Reported by Le Huy | February 16th, 2008 @ 09:13 PM
try to change IO::BufferSize to lets say 16 then run and see
bin/ci -t x spec/ruby/1.8/core/io

I don't know if this is a bug or not. While changing the buffer size should have no effect, it's not something that's exposed to the end user.

It just shows that there is some problem related to using read buffer in IO code. Since most of IO spec using small files with size less then IO::BufferSize, hidden bugs are not detected when running spec.

The IO buffer is set in the builtin class (i.e. in C++), so this should no longer be an issue. Reopen if it is.
