Subject: [ruby-core:19668] [Bug #703] string output duplication occurs if the same file descriptor written to in different threads

Bug #703: string output duplication occurs if the same file descriptor written to in different threads
http://redmine.ruby-lang.org/issues/show/703

Author: Roger Pack
Status: Open, Priority: Normal

ruby-dev:32566

a = Thread.new { p '4'}
b = Thread.new { p '3' }
a.join
b.join

results in
"4"
"3"
"4"
"3"

because the buffer is modified simultaneously by two threads within io_fflush [I think].
