Issue #1332 has been updated by Roger Pack.
Appears that
1) the writes have slowed down, "only" by about 100% (take twice as long to write in ascii 1.9 as in 1.8). Not terrible.
2) the reads have slowed down by something like 40000% (!)
I think to avoid the slowdown with reads you can "hack a work around" like
c = File.open('out.file','rb') { |f| f.read }
c.gsub!("\r\n", "\n")
But this seems like there might be a bug in there, too.
